Chapter 2

“It’s not often for one’s secondary gender to change, but it sometimes happens to Betas like Ms. Park Sia who have a severely compromised immune system. I even had a patient who changed from a Beta to a recessive Omega after suffering from COVID for two weeks.”

In front of the doctor, who spoke in a tone suggesting this was surprisingly common and nothing serious, Sia found it difficult to continue her detailed questions.

Embracing her confused state of mind, she had no choice but to accept the fact that her secondary gender had changed overnight.

‘Is this a silver lining? A recessive Omega.’

The fortunate thing was that she had presented as a recessive Omega, which wasn’t significantly different from a Beta.

The doctor explained that recessive Omegas usually didn’t have a high chance of conceiving, and if they were lucky, their heat cycles wouldn’t be severe. They could live pretty much the same as a Beta if they just took their suppressants regularly.

Sia mulled over the doctor’s words and tried to soothe herself.

‘For now… I should probably hide it. The moment I let it be known, I’ll probably lose my tutoring job.’

The hospital kindly explained the procedure, stating she needed to visit the district office within a week to update her ID. However, she was deeply reluctant, feeling like everything would truly change the moment the “Omega” stigma was stamped on her ID card.

Unseen discrimination and inconvenience certainly existed the moment one was classified as an Omega. Although the rights of Omegas had improved significantly compared to the past, they were still fighting against invisible discrimination.

The most common example was that Omegas found it much harder to find employment compared to Alphas or Betas. Because of this, people who presented as Omegas sometimes chose not to officially register their secondary gender. Although they faced a fine if caught, it seemed there were still quite a few people who chose to live pretending to be Betas, accepting the risk.

Naturally, Sia, who had lived her entire life as a Beta, felt this even more strongly. Even after being told her secondary gender had changed to Omega, it didn’t feel real because she looked no different than she had yesterday.

The biggest hurdle was preparing for the heat cycle, which she had never experienced before. Typical Omegas had gone through their heat cycles since secondary maturity, knew their cycles, and had learned how to safely manage them. But for Sia, who became an Omega overnight, everything was unfamiliar and confusing.

‘Yeseo is an Omega, so maybe I should ask just her beforehand…?’

Sia thought of her closest friend, Yeseo. Yeseo, a friend since elementary school, was the only Omega among Sia’s circle of friends.

RRRRRRR-

She was debating whether it would be best to tell only Yeseo honestly when her phone suddenly rang loudly. She hastily looked at the screen, wondering if it was a message from Junik, but it was a call from her mother, contrary to her expectations.

“Sia. Did you call Jihoon to thank him?”

“Uh… not yet.”

“Look at you. It’s been a week already, and you still haven’t properly thanked him? Shouldn’t you at least buy him a meal? Jihoon carried you on his back and ran to the emergency room—doesn’t his muscles ache?”

At her mother’s worried voice coming through the phone, Sia let out a deep sigh.

‘Mom. It hasn’t even been a week since your daughter was discharged, and you’re worried about Jihoon instead of her? And he’s an Alpha, an Alpha! He’s the type of obnoxious jerk with genetics that wouldn’t even get sore muscles if he carried me up the peak of Bukhansan*!’

[*T/N: mountain on the northern edge of Seoul]

These thoughts surged to the tip of her tongue, but Sia swallowed her true feelings in front of her mother, who doted on Jihoon.

“I did text him, but things were hectic so I couldn’t call. After I was discharged, I had a continuous fever and was dizzy for a while, so I was busy recuperating.”

“Then why did you drink so much, you silly girl? That’s all your own doing. You are cutting out alcohol for a while. Understand?”

“Yes.”

“Did you thank Jihoon’s cousin, his doctor? That hospital is Jihoon’s maternal family’s hospital, right?”

“Of course, I properly thanked the doctor… Anyway, I have to go, Mom. I have an exam today. I’ll buy Jihoon a meal separately or something.”

“Okay, be nice to Jihoon. You won’t find another guy like him.”

It seemed her mother wasn’t worried that her only daughter had collapsed and been rushed to the emergency room. Her mother, whom she’d expected would at least send a bowl of porridge, just nagged her, as expected.

Her mother, who was born a recessive Omega, had been prone to illness since Sia was young. She often collapsed with the flu, and whenever the family went on a long outing, she would inevitably spend the next day sleeping all day in bed. Sia’s Alpha father was busy taking care of her physically weak mother.

Perhaps due to this environment, there was never a single family member who warmly nursed and cared for Sia when she caught a cold or felt sick. Crying out that she was sick in front of her sickly mother felt like a dereliction of her duty as the eldest daughter. Because of this, Sia had developed a habit of keeping her mouth shut and enduring it alone whenever she was sick or having a hard time since she was a child.

Sia suddenly recalled a day in elementary school. The day she got terrible indigestion after eating the spaghetti served for lunch. It was the obnoxious Kang Jihoon who carried her, collapsed near the cafeteria, to the nurse’s office.

“Are you a pig? I knew you were doing a mukbang with the spaghetti. Does it make sense to get indigestion from overeating that tasteless spaghetti? Do they starve you at home?”

“Get lost. I don’t have the energy to argue with you…”

“Park Joraeng, wouldn’t it be better to just leave school? Why are you trying so hard to stay in the nurse’s office? Or just go to the hospital and get an IV. Saline is the best. Should we go to my cousin’s hospital? I’ll talk to the teacher using my class president authority.”

“…No, thank you. I’ll be fine if I take medicine and sleep. I don’t want to show my mom that I’m sick.”

“Why?”

“Ugh… you don’t need to know. It’s just how it is. I’m going to sleep, go away.”

She turned her back and tried to sleep, not wanting to talk to him anymore. When she woke up after a nap, Kang Jihoon was waiting, staring at her, having even brought her school bag. That day, thanks to Jihoon, Sia was able to travel comfortably home in the large, black car driven by his chauffeur.

As this forgotten memory from her childhood returned, she felt it was right to properly thank him this time.

However, she hadn’t seen Kang Jihoon since the day she was taken to the emergency room. Jihoon, who would consistently visit her house at the scheduled time every week, hadn’t shown his face during the exam period, claiming he would use the library instead. Sia found herself subtly bothered that the guy who used to pop in and out so frequently hadn’t shown his face even once since taking her to the emergency room.

“Kang Jihoon, surely… he doesn’t know I became an Omega and is avoiding my house now, does he?”

The hospital she was admitted to was run by Jihoon’s maternal family, and the doctor who told her about her secondary gender change to recessive Omega was Jihoon’s maternal cousin. It wouldn’t be strange at all if the fact that her secondary gender had changed to Omega had accidentally reached Jihoon’s ears.

“Does he think some kind of accident will happen if he’s around me? What an absurd jerk! I wouldn’t touch a shallow guy like you, Kang Jihoon, even if you offered yourself up!”

The fact that Kang Jihoon, who had been visiting her house after paying fees, had suddenly decided to use the library right after her secondary gender changed to Omega… Sia felt unnecessarily angered, feeling like she had been cut off for being an Omega by the person she had no romantic interest in—no, the person she despised most in the world, Kang Jihoon.

‘Ugh. Whatever. I should just go to school.’

Today was the final exam day. Was it because not much time had passed since her secondary gender changed? Starting this morning, she felt a slight fever again and shivered with chills, just like the onset of a cold. When she preemptively took medicine when a cold was about to strike, it usually didn’t get severe and she quickly got better.

Sia ate a simple breakfast, swallowed the herbal cold medicine she usually took, and diligently took Vitamin C.

“Junik still hasn’t contacted me. I guess the ‘flirtationship’ is over again.”

Sia recalled Junik, who hadn’t contacted her at all since the day she was hospitalized. She regretted that the sweet, fleeting conversations they had were gone, wondering if she had somehow deleted their chat window while heavily intoxicated that day. A worry surfaced that she might have made a mistake while drunk, but she was surprisingly calm, feeling that what was coming had come, as her contact with crushes had been cut off like this countless times overnight. She just felt it might be a little awkward if they ran into each other when she went to her tutoring job.

As she glanced around the house, thinking she was ready to leave, the suppressants prescribed at the hospital caught her eye.

“It’s dangerous since you don’t know your heat cycle yet. I recommend taking the suppressant immediately if you feel even the slightest unusual signal in your body.”

Sia took a few pills out of the container, which was half the size of her palm, and stared at them. Although she hadn’t lived as an Omega, she knew about the heat cycle from sex education. When a heat cycle came, she knew one would feel such an intense, strange sensation that it would be hard to control one’s body, and reason would be paralyzed, feeling like one would die if they didn’t have sex immediately. And if they smelled an Alpha’s pheromones, they would desperately cling to that person, no matter who it was.

She roughly knew what the symptoms felt like, having seen classmates in the hallway several times who were in distress due to a sudden heat cycle in middle and high school. Even the sharp-witted Yeseo, who was just as sensible as Sia, had experienced trouble due to a sudden heat cycle during a school trip.

However, the suppressant, which she had never taken in her life, simply wouldn’t go down her throat.

‘I’ve been taking strong medicine for days now, and there are absolutely no heat cycle symptoms, so I really don’t want to take the suppressant preemptively…’

Sia looked at the thumb-sized, white hexagonal pill resting on her palm. The large pill, which looked difficult to swallow at a glance, was enough to cause aversion in her, as she was seeing a suppressant for the first time.

She had nowhere to go except school and home, and she figured she could quickly swallow the pill if an emergency situation arose. Moreover, her house was only a five-minute run away from school. Sia, who had never experienced a heat cycle before, naively thought that she could handle it herself, even if a heat cycle suddenly arrived.

***

Given that she’d been hospitalized and in poor condition, unable to study properly, she did quite well on the exam. No, honestly, she thought she’d done quite well—well enough that losing her scholarship felt unfair.

Maybe it was because she’d worn a thick mask, thinking she might have a cold. Contrary to her worries, the pheromones of the Alphas she passed by didn’t feel as strong as she’d feared.

‘There’s an hour until the next exam, so I should find an empty lecture hall and go over the past exams one more time.’

Sia looked around for an empty classroom, dragging her body, which felt as heavy as waterlogged cotton.

She’d definitely taken cold medicine this morning and even remembered to take her vitamins. Yet, unusually, her low-grade fever stubbornly refused to subside.

‘I guess since I was taken to the emergency room and even went through a secondary gender change… slow recovery is inevitable.’

With heavy steps, she entered an empty lecture hall, found a seat, and opened her book.

A drowsy, languid feeling washed over her as if sleep would overtake her at any moment, but all she wanted was to review at least one word before the next exam.

But something was strange.

The moment she sat down in the chair and exhaled deeply, a tingling sensation like heat waves began to slowly crawl up from her toes toward her navel.

‘…What is this?’

It felt as if an invisible, large hand was slowly, warmly caressing the inside of her thighs—a strange, arousing feeling began to bloom.

“…!”

Suddenly, unlike the ticklish sensation from moments before, a raw surge of lust crashed over her delicate body like a wave.

As an involuntary moan escaped her lips, Sia hastily covered her mouth with her small hand.

As if something thick and long like a snake was stickily caressing between her legs, an itchy sensation began to spread in her inner thighs.

Just like when she’d secretly held her breath while reading erotic comics, she could vividly feel the secret area on the inside of her thighs growing wet.

Sia frantically looked around before groping downward with her hand. At the sticky sensation against her fingertips, she shot up from her seat.

Like she’d wet herself, the area below her gray sweatpants was sticky and soaked through.

‘Oh god. Am I losing my mind?!’

The moment she saw the slick fluid staining the chair where she’d been sitting, Sia snapped to attention as if doused with cold water.

She’d never experienced it before, but she knew instinctively.

Her heat cycle had hit.

“Wh-what do I do?”

At this sudden abnormal change in her body, Sia stomped her feet anxiously.

To make matters worse, a sweet apricot scent completely different from the perfume she’d sprayed on at home began wafting from every corner of her body.

At the unfamiliar pheromones emanating from her body, she frantically gathered her things and rushed up to the top floor of the college building, afraid someone might come.

If she stayed in the empty lecture hall like this, she might face danger from an Alpha who caught her pheromones and came looking.

At this strange fear she was experiencing for the first time in her life, Sia trembled all over like a leaf.

Instinctively, a bright red warning signal blared loudly in her head.

She hurried into the faculty restroom on the fifth floor. She planned to at least quickly deal with her soaked sweatpants in the bathroom and take her suppressants.

The last thing she wanted was to walk around campus making it obvious she was an omega in heat.

The fifth floor at the top of the college building was practically empty except for two professors’ offices.

Because of this, hardly anyone ever came up there, except for the occasional student who went to the roof to smoke.

Sia barely clung to the thread of her sanity amid the increasingly intense unfamiliar pleasure, and hurriedly went into a bathroom stall.

She pulled off the thick mask that had been covering her nose and mouth, and sat sprawled on the toilet seat. There was no water, but all she could think about was that she needed to take her medication as fast as possible—even one second mattered.

She frantically tried to pull out the suppressants she’d portioned into a container from her backpack, but her hands kept trembling so badly that even opening the light plastic case proved difficult.

“Gasp, no!”

The moment she managed to pry the pill container open with her fingernails, there was a soft thunk, and the white pills inside tumbled out and clattered to the floor.

The thumbnail-sized pills that had fallen beneath the stall partition rolled across the ground before coming to a stop against a pair of familiar brand sneakers.

From beyond the bathroom door, where her gaze had landed, an all-too-familiar voice drifted in.

“Park Joraeng.”

The voice, a low baritone tinged with amusement, belonged to none other than Kang Jihoon.

“What are you doing going around school like a bitch in heat? Your pheromones were so strong they were spreading outside the bathroom, so I came to check… What would’ve happened if someone other than this oppa had found you?”

His voice sounded strangely pleased, and Sia felt a surge of anger.

But unlike usual, her voice kept coming out mixed with moans, making it difficult to even argue back against his nonsense.

“Th-this is the women’s bathroom. Are you insane?”

“Huh? This is the men’s bathroom.”

“What?”

Sia jumped up like a startled fish.

In her frantic rush to get inside, she’d failed to properly check the restroom sign.

But she couldn’t afford to keep bickering with Jihoon here.

If her pheromones had spread outside the bathroom like he said, it wouldn’t be strange at all for other Alphas to come swarming after catching the scent.

The last thing she wanted—even if it killed her—was to be immortalized on Eta as “Park Sia, the Literature Department nuisance who transformed into an omega, didn’t self-report, and went around leaking pheromones everywhere.”

More than anything, she could feel the last shred of her rationality growing hazy from the dense pheromones of the extreme dominant Alpha wafting from beyond the thin partition.

If she dragged this out any longer, the disaster of her spreading her legs and wailing in front of Kang Jihoon—the person she hated most in the world—might actually come to pass.

Suppressing the wave-like, shimmering sensations that kept surging through her, Sia pleaded with Jihoon standing outside the stall.

“Ngh, K-Kang Jihoon. Give me the suppressants. Please. If I don’t take them, hah, something really bad might happen… okay?”

“Then say ‘please give them to me.'”

At her voice, unusually laced with faint whimpers, a snicker leaked from beyond the partition.

“Hah, please, stop messing around…”

“I’m not messing around. I told you, say ‘please give it to me.'”

“Hngh, you, seriously…!”

At Jihoon’s repeated teasing tone, tears finally rolled down Sia’s large eyes in fat drops, like chicken droppings.

The fact that this situation—where she felt extreme terror as if her very survival was threatened—was nothing more than entertaining spectacle to someone, like some kind of variety show, was utterly humiliating.

She resented herself from a few hours ago for not listening to the doctor and taking suppressants in advance, and she hated this peculiar, unsettling sensation that had suddenly descended upon her—it was unbearably unpleasant and revolting.

But what was even more infuriating was the humiliating reality that she had to humble herself and beg the male friend she despised most in the world.

Just like that day in the past when she’d studied all night until her nose bled but still lost to Jihoon and bawled her eyes out, a crushing sense of shame crashed over her like a tidal wave.

“Little dumpling. I told you, say ‘please give it to me.'”

“Sob, sniffle, crazy bastard.”

“Ah. Guess you don’t need the suppressant after all? If you don’t listen to this oppa and end up getting fucked by some trash Alpha, that’s not my problem.”

Kang Jihoon, who would normally tease her endlessly and act playfully, spoke in a flat voice, as if he didn’t have even a speck of lingering attachment.

Bang—

Suddenly.

As he turned to leave without a moment’s hesitation, Sia instinctively flung open the stall door and grabbed Jihoon’s forearm.

Her instincts acted before her brain could catch up—she knew that if Jihoon took the suppressant away from her now, she’d be in real trouble.

“K-Kang Jihoon, hic, my… my suppressant…”

Through the open doorway, their gazes became entangled like chains.

At his arrogant, dark eyes, her small hand—which had been gripping his firm forearm—loosened its hold in fear.

Frightened by Jihoon’s chilling gaze—which, unlike usual, held a strangely golden tint—Sia shrank back and took a slight step away.

Jihoon’s gaze flickered eerily, like a predator that had spotted its prey.

“Wow, you… you’re a fucking sight to behold.”

Watching Sia tremble while clutching her chest with her small hand, Jihoon let out an involuntary exclamation of admiration.

Park Sia, soaked in pleasure and howling in the throes of her heat cycle—the sight was even more fantastic than he’d imagined.

Her red eyes brimming with tears and her small hands shaking uncontrollably stirred his sadistic urges.

The front of her gray tracksuit, already soaked through and spreading in a round stain, was quite a sight to behold.

He’d been secretly curious what kind of pheromones Park Sia would emit once she presented as an omega. A luscious, fragrant apricot scent filled the cramped bathroom.

The scent was sweet and stimulating, incomparable to the countless omega pheromones he’d encountered before.

“Please… hah, g-give it to me.”

A moan-laced plea escaped from between Sia’s tightly pressed, plump lips.

Jihoon’s thick, handsome eyebrows arched as high as they could at the sight of Sia trembling like a small animal, holding out her tiny hands.

Park Sia, who would normally charge at him with her claws out like a wildcat, was now politely extending both hands in supplication.

“What was that? I couldn’t quite hear you.”

“Hnngh, p-please… give it to me. Please…”

The moment he saw Sia looking up at him with her nose flushed red and sniffling, Jihoon’s lower half swelled even hotter.

Truth be told, things below his waist had never been at ease from the start.

His cock, which had been swelling from the moment he caught her pheromones, was screaming to plunge inside the omega before him right this instant.

Since that childhood day when he first felt possessive of her, he had never once relieved his lust with any woman but her.

He’d spent countless nights awake, jerking off while imagining Park Sia pinned beneath him, her cute little hole twitching.

From the day he first became aware of her, how much heartache had he endured trying to suppress these feelings that burned hot as a fever?

Because he didn’t want to sleep with anyone but her, he’d always taken care of his own urges, and as a result, the toxicity of being a dominant Alpha had been building up in his body, layer by layer.

He was still young enough to get by with medication for the severe migraines and hormone regulation, but it was obvious that if this kept up, it would take a serious toll on his body.

Yet just the thought that he would soon be rewarded for all the pain he’d endured until now made his groin ache with heat and heaviness, his cock throbbing.

“Good girl.”

Watching Park Sia obediently follow his every word, Jihoon barely suppressed his explosive instincts and gave a small smile.

“Park Joraeng, hold on tight to me.”

“Haht, mmh… mmph…!”

He lifted Sia up from where she’d been sprawled against the toilet and pulled her into his arms, letting her lean against him. Then he closed the stall door and held her even tighter.

“Hah, your pheromones… they’re so good. Fuck, they’re so sweet. Sia.”

“Hff, mmnh… nnh.”

The dominant Alpha’s intoxicating pheromones flooding her senses made Sia nod weakly, her eyes half-glazed.

Any rational thought about needing to take suppressants had long since fled.

The pheromones pouring from the firm, large body enveloping her felt so euphoric that she grew even more aroused.

“Hhht, ah… Jihoon, Jihoon…”

Before long, Sia—completely intoxicated by Jihoon’s pheromones—began to moan and started touching her wet pussy herself.

Like any omega who’d completely lost their reason to an Alpha’s pheromones, Sia seemed utterly unaware of what she was doing right now.

Watching her fidget with her small hands as she touched her pussy, Jihoon let out an admiring laugh.

“Hoo, Park Sia, are you touching your pussy yourself right now?”

“Weird, hff, weird, nnh…”

As the strange sensation that felt like it would burst kept overwhelming her small body again and again, Sia clung helplessly to Jihoon’s body.

The instinct to be freed from this monstrous heat as quickly as possible—even by a single second—seized her.

“Jihoon, hff, I… ah, it’s hot down there. Nnh, please, do something… hhk…”

“Your pussy, is hot?”

“Hht, mmph, yeah…”

“Park Sia. Say it properly with your own mouth. Your pussy is hot?”

“Hff, uh, Jihoon, hht, pu… pussy is, hot… nnh.”

Overwhelmed by her first heat cycle and not knowing what to do, tears suddenly spilled over from her large eyes.

“Fuck.”

At her pitiful and adorable movements, Jihoon let out a rough breath and slipped his large hand inside Sia’s thin t-shirt.

“Looks like your breasts are getting hot too. Your tits are hot, Sia.”

“Hht, yeah…!”

“Like they’re begging to be sucked… Cute, aren’t they?”

The soft, squishy sensation that fit perfectly in his hand felt so fucking good, he thought he might cum right then and there.

Jihoon kneaded her breasts like dough before slipping his hand inside her bra.

Thinking that someday he’d like to lock her in a room and spend all day just sucking on these perky tits, Jihoon tormented her by twisting and pinching her nipples.

“There, hht, I, I like it… mmh…”

Normally, those tiny fists should have come flying at him like a kitten’s soft paws. But Sia, already completely intoxicated by Jihoon’s pheromones, surrendered her body to the pleasure he gave her and thrust out her breasts as if begging for more.

Finding Sia’s pleading form unbearably adorable, Jihoon felt his lower body throb painfully, ready to burst.

“Joraeng, you like it when I touch your tits?”

“Nnh, yeah, I like it, I like it, hff…”

“Fuck, you like it? Me touching your tits?”

“Hht, uh, yeah… I, I like it. Jihoon, ah…!”

Jihoon buried his face in her breasts and sucked on those luscious tits like a nursing child, suckle, suckle.

As Sia twisted her waist from the strange pleasure at the tips of her nipples, Jihoon gripped her delicate body tightly with both large hands and mercilessly bit, sucked, and licked her breasts.

Sia’s moans and the obscene sounds of him greedily sucking at her flesh echoed lewdly through the cramped bathroom.

“Hngh, ah, ahng, hff…!”

“Haa, ha…”

If he had his way, he’d strip her bare right now and lick and suck her everywhere, even that tight little hole between her thighs. But he couldn’t have his first time with his precious girl in a place like this.

Jihoon exhaled roughly, suppressing the explosive sexual desire swirling inside him as much as he could.

“If I’d known you were this eager, I would’ve done it sober that day.”

“Ngh, what do you, hff…”

“Kuk, you’re so cute. So damn innocent.”

As if finding her adorable for being too drunk to remember anything, Jihoon reached down and grabbed the front of her soaked clothes.

After rubbing the already damp training pants a few times and pulling them down, the shape of her plump vulva was explicitly revealed through her soaked cotton panties.

“Sia, you know what?”

“Hngh, mm…”

“Your pussy’s so fucking plump. All that delivery food you ate must’ve gone straight here.”

“Haa, ngh, there, hff…”

As Jihoon vigorously rubbed the center of the plump flesh over her panties with his long, firm fingers, slick arousal flowed out ceaselessly in sticky streams.

Just when he thought he might truly lose his mind, drunk on that sweet apricot scent, just then—

“Hey, do you smell something?”

“Huh, yeah. Isn’t that omega pheromones?”

Suddenly, the murmuring voices of people heading to the rooftop for a smoke drifted in from outside the bathroom.

“Hff…!”

Startled by the unfamiliar Alpha pheromones and voices, Sia suddenly looked outside the bathroom.

Even as her mind was already hazy from Jihoon’s pheromones, the moment she sensed the noxious pheromones of unfamiliar Alphas, a strong sense of revulsion welled up inside her.

Jihoon’s pheromones—cool and deep like a forest—felt endlessly pleasant and intoxicating, but the unfamiliar Alpha pheromones weaving through them were unbearably noxious and unpleasant.

It was as revolting as smelling cheap, overpowering perfume.

It was truly strange.

“Ngh, no, I don’t like it…”

“Don’t like it? The other Alphas’ pheromones?”

“Hff, hngh… yeah.”

Sia instinctively pressed herself tightly against Jihoon’s body, trembling and curling up.

“Heh, you’re clinging to me because you hate other Alphas’ scent?”

“Hngh, don’t like it… ngh…”

“Ha, fuck. Why are you so damn cute… huh?”

The omega instinctively burrowing into his arms at the unfamiliar Alpha scents was unbearably adorable, and Jihoon barely swallowed down the ticklish laughter that kept trying to burst out.

This was what he’d wanted to see. Park Sia, so accustomed to his pheromones that she felt repulsed by other Alphas’ scents. That’s why he’d been flooding her cramped room with his pheromones all this time, using the flimsy excuse of free periods.

All his efforts seemed to be paying off, and bells of triumph rang through Jihoon’s mind.

Park Sia was a beta, so naturally she couldn’t smell his pheromones, but the massive amount he’d been releasing over such a long period had undoubtedly accumulated inside her body, layer upon layer.

Day after day, Sia had eaten, studied, showered, and slept while breathing in the dominant Alpha pheromones that Jihoon had saturated her tiny studio with.

For her to find other Alphas’ pheromones unpleasant was only natural.

“Park Joraeng, you’re leaking pheromones here like this—it’s like advertising for Alphas to fuck you. You’d have no right to complain if some random Alpha you’ve never met suddenly fucked you.”

He said words he didn’t mean to the small-animal-like omega trembling in his arms, threatening her.

Any Alpha with proper moral standards would never enter the women’s bathroom, no matter how strong an omega’s pheromones were. But the despicable Jihoon used false information to stoke Sia’s fear to its peak, driving her into a corner.

“Joraeng. What do you think would happen to you if I just left you here and walked out?”

“Jihoon, Jihoon. Don’t do that. Hup… Don’t do that.”

At Jihoon’s brazen lie, Sia trembled and clutched his forearm with her small hands.

That pitiful, fragile gesture was unbearably adorable, and Jihoon’s cock, already swollen to bursting, swelled hot once more.

“Hoo, how do you want me to help you?”

“Don’t go. Hup, hup… I’m scared, I’m scared.”

“Do you need me that much?”

“Y-yes. Please, Jihoon, hup…”

Kang Jihoon roughly ground the front of his pants, swollen to its limit, against her leg as he asked.

“If I protect you, will you take care of my cock?”

The thick, menacing bulge over his pants was, at a glance, massive—like a weapon.

Sia looked at the hard front of Jihoon’s pants grinding violently against her body, her face filled with fear.

“Hm? Sia. I’m asking you. Will you take care of my cock?”

“Hup, y-yes.”

But Sia, her reason completely lost in a mix of arousal and fear, nodded her head vigorously.

As if the Alpha before her eyes were her only refuge, she gripped Jihoon’s firm forearm even tighter, sending him pleading looks so he wouldn’t leave her behind.

“You’re promising? No taking it back later this time?”

“Hup, yes, yes.”

When Sia nodded repeatedly, Jihoon pulled her into an even tighter embrace, the corners of his lips curling up in satisfaction.

Suddenly, powerful apex Alpha pheromones poured over her delicate body.

The intense pheromones drenched her like a downpour, and Sia gasped for air, her entire body thrashing as if struck by lightning.

“Wh-what are you trying to… hup…!”

“Shh. Park Sia. Stay still.”

Just like that night when he’d thoroughly smeared his semen, covered in pheromones, all over her drunk, pale body.

Just like that night when he’d held her unconscious form and relentlessly flooded her with his powerful apex Alpha pheromones for hours on end, ultimately turning her into an omega.

Jihoon held the trembling little woman even tighter, pouring his pheromones powerfully over Sia’s entire body.

The cool, heavy scent of deep forest spread through every cell of her body, wrapping around her small frame like chains.

“Hey, hey. I think this time it’s Alpha pheromones…?”

“Crazy. Are they fucking in the bathroom?”

As the Alpha’s pheromones covered hers, the Alphas who’d been lurking near the bathroom quickly lost interest as if nothing had happened and moved away, heading to the rooftop.

Along with a wave of relief, Sia felt a strange sense of déjà vu.

“Jihoon, this is weird. Haa…”

“Hm? What is?”

It was because hazy scenes of something similar happening before floated up faintly in her mind.

“I definitely… with you, ngh, I remember doing this…”

“Park-Shorty. Did you masturbate while thinking about this oppa?”

When Sia made a strange expression as if remembering something, Jihoon caught that fleeting change and sharply pulled her by the nape of her neck.

Then he swallowed her plump lips whole.

“Mmph, mm, mmh…!”

A lewd kiss continued, their tongues tangling and intertwining.

As his thick, hot tongue explored every corner of her tender mouth, Sia clutched Jihoon tightly with her small hands and swallowed the saliva he fed her.

“Haa, hup…”

Even though it was just their lips touching, unbearable pleasure surged through her. Strange sensations spread to every corner of her body, and the area below her navel itched unbearably.

But it was strange. She felt like this wasn’t her first kiss with him either.

“Jihoon, Jihoon…”

“Yeah. I’m Jihoon.”

Their lips parted, and indistinguishable saliva stretched between them in an arc.

Filled with excitement, Jihoon pulled the small omega into his arms as she desperately called his name and showered her face with kisses.

Even after holding each other tightly and deeply sharing their saliva, it still wasn’t enough.

Sia felt the same way.

As she was completely drenched in the pheromones of the dominant Alpha and even drank the saliva he fed her, only the omega’s primal instinct dominated her.

Sia clung to Jihoon like a baby koala as he held her, continuously rubbing between her legs against his firm thigh.

Jihoon’s weapon-like length, hard and pressing near her navel, rubbed roughly against her.

“More… do more. Touch me, mm, ah…”

Sia’s small hand gripped his large hand and placed it on her perky breasts.

“Hah, fuck.”

As the small, white fingers he usually found so adorable pulled his hand to make him touch her breast, a rough metallic sound escaped through Jihoon’s teeth.

“Park Sia… why are you so fucking lewd, huh?”

“Do more, Jihoon, ah… I need, I need something, mmh…!”

“Hah, fuck. I’m going crazy.”

In front of the adorable omega who was desperately calling his name and begging to be penetrated, Jihoon could almost hear the sound of his reason snapping.

“Joraeng, you were the one who egged me on, weren’t you?”

He’d reached his limit.

***

“Mmph, ngh, ahh…”

After that, she couldn’t remember how she got home.

Jihoon slung the feverish, disheveled Sia over his shoulder and quickly carried her to her studio apartment.

Whether fortunate or unfortunate, her studio was fairly close to the back gate near the College of Liberal Arts.

Classes were in session, so few people were around, and thanks to being covered in Jihoon’s pheromones earlier, Sia’s own pheromones weren’t noticeable to other Alphas.

But Jihoon, driven to extreme arousal by Sia, was suffering as much as if he were in rut.

Those five minutes of running with her slung over his shoulder were arguably the most patience-testing moments of all the countless hours he’d endured until now.

“Haah, ngh, mmm…”

As soon as they entered the studio, Sia collapsed in the entryway and Jihoon embraced her. The two shared a fierce kiss, neither one taking the lead.

Their tongues rubbed and ground together fiercely. Lips crashed together frantically as saliva mixed.

The small room grew stuffy with rising heat, as if the heater had been cranked up full blast.

Jihoon’s large hands roamed ceaselessly over Sia’s delicate body before he pulled off her sweat-soaked t-shirt, exhaling roughly.

“Hah, Park Joraeng, let’s take off our clothes.”

“Mmph, ngh…”

Already drunk on arousal and unable to grasp her situation, Sia shed her cumbersome clothes as Jihoon’s hands guided her.

In an instant, they were both down to their underwear.

With urgent movements, Jihoon unhooked her plain apricot-colored bra.

Though this wasn’t his first time removing her bra, his touch remained clumsy and rough.

The moment he removed her bra, her perky breasts—just the right size to fill his hands—bounced free. Seeing them openly like this with their owner’s permission brought a satisfaction on an entirely different level from all his previous glimpses.

“Sh—…”

Her pale breasts with their light-colored nipples looked as luscious as ripe fruit.

Those pale breasts, marked with reddish traces from being bitten and sucked repeatedly in the bathroom, looked so soft, he felt he could keep them in his mouth and suck on them all day without ever getting tired.

“Hah, this is driving me crazy.”

Jihoon let out a dry rasp as his large hands urgently pulled off her panties.

As he slid down the panties already soaked with her juices, slick transparent fluid dripped in an arc.

Over her pale, smooth thighs, the juices she’d already released in abundance trickled down in streams.

From within the plump flesh where neat pubic hair nestled, an irresistibly sweet apricot scent wafted.

Even though this wasn’t the first time he’d stripped Sia of every stitch of clothing to see her naked body, his heart raced helplessly out of control.

That night when she’d been drunk. Like that first night when he’d undressed her sleeping form and saw her naked for the first time. Once again, admiration spilled out unbidden.

Below her tiny face, her long slender neck and protruding collarbones, her perky breasts that filled his large hands. Her pelvis, quite voluptuous compared to her slender frame, her long, straight legs… Every part of Sia’s naked body was flawlessly beautiful.

But what excited Jihoon most of all were the dainty hands and feet attached to that delicate body.

How many countless nights had he indulged in obscene fantasies of those hands gripping his cock? How many times had he thought about rubbing his cock against those tiny feet?

Was it the anticipation that in just a few seconds he’d be able to freely indulge in all the obscene acts he’d only imagined in his head? Her lewd appearance kept making the front of his underwear bulge, his cock chafing against the fabric until it stung and ached.

“Hah… Joraenge. You’re so fucking pretty. You know that?”

“Hngh, mm…”

Jihoon exhaled roughly as he forcefully spread her thighs apart with his large hands.

The tight hole puckering and dripping with arousal was unbearably adorable.

After stroking her soft, cat-fur-like pubic hair several times, he ravenously buried his face in her plump pussy.

As his sharp nose touched the tight hole, Sia’s pheromones spread throughout his body as if permeating every single cell.

“Haah, hah…”

The sweet, lovely apricot scent felt like it would paralyze Jihoon’s sense of smell.

Jihoon pulled down his already damp black drawers and pulled out his cock.

His dark red cock, veins bulging prominently across its surface, was swollen to its limit, desperate to plunge into Sia’s tight hole.

The rigid shaft standing beneath the thick, coarse black pubic hair, along with his heavy balls… It looked as thick as Sia’s forearm—at a glance, no different from a weapon.

“Fuck, Sia, why are you so beautifully wet? Hm?”

“Hngh, mm…”

“You’re trying to drive me crazy on purpose, aren’t you?”

Jihoon pressed soft kisses—chu, chu—against the red flesh already drenched in her juices, then gently licked between her folds with his tongue.

“Jihoon, hngh, there, ah…!”

When he teased the protruding clit at the top of her plump pussy lips with his tongue, even more desperate moans spilled from Sia’s full lips.

“Ji, Jihoon, ah, ngh, ah!”

“Fuck, even your moans are so damn cute.”

Just licking her pussy was enough to get her this worked up. Seeing this small-animal-like woman trembling all over from his touch made Jihoon find her all the more adorable, and he lapped at her pussy all the more, as if to show off, like a dog.

After licking her entire pussy with his tongue for a while, he showered her tiny clit with kisses—chu, chu—and teased it with the tip of his tongue.

Indulging in the filthy fantasy of soon slathering this cute pussy with cream and savoring it, he caressed her red flesh as if biting into a luscious fruit.

“Jihoon, there, hngh, it, it feels good…!”

Her words of pleasure excited him even more, and Jihoon pushed his thick tongue firmly, again and again, into her tight hole.

The warm, supple inner walls he felt against the tip of his tongue felt so fucking good that he was going crazy wanting to shove his cock inside right now.

“Jihoon, hah, ngh, mm…!”

Her delicate body, faithfully responding to the stimulation he gave, kept releasing wetness again and again.

Jihoon licked up all the wetness dripping down to her thighs, exhaling roughly.

Sia, who had lost even the last thread of resistance from his earlier caresses, obediently spread her legs wide and whined for him.

She bucked her hips on her own, pressing her pussy closer to his lips, begging him to do filthier things.

“Good, Jihoon, hah, good… More, do it more, mm…”

“Hah, fuck.”

Park Sia, who always gave him the stink-eye and looked at him with disgust whenever she saw him, was now spreading her legs wide on her own and begging him to do filthier things. It was nothing short of a moving moment.

Most of all, why did the word “good” flowing from Sia’s lips make his chest tingle so much?

Jihoon barely suppressed the emotions welling up inside him and spoke in a wheedling tone.

“Sia.”

“Hah, mm…”

“Call me honey.”

“Jihoon, hurry… mm…”

“Hm? Call me honey, Sia.”

Jihoon rubbed his face against her soft pubic hair as he caressed her tight entrance with his long fingers.

He felt a little petty taking advantage of an omega so lost in arousal she didn’t even know what she was saying, but all he wanted was to use this opportunity to hear the term of endearment he’d longed for from her.

When Jihoon only teased around her tight entrance without giving her more stimulation, Sia, desperate for greater pleasure, twisted her hips and managed to force out the word he wanted.

“Hah, h-honey… Hurry… mm…”

“Hah… I’m seriously going crazy.”

At the word “honey” spilling from Sia’s lips, Jihoon growled like a beast and gripped her slender waist hard.

He could feel heat rushing back to his cock, even though he’d thought he’d already reached his limit.

The tiny woman before him was so lovable, so adorable, so beautiful. A violent surge of lust rose within him—an abnormal thirst that felt like it could only be quenched by biting and licking every inch of her small body.

Jihoon roughly grabbed her pale breasts with both large hands as he frantically showered her neck and armpits with fierce kisses.

“Haah, Jihoon, hng, mm…!”

“Hah, fuck, call me, call me honey. Hng.”

“H-honey, hng, ah, aah…!”

Her neck, armpits, waist, navel, inner thighs… Red marks from Jihoon’s biting and sucking drew an obscene map across every inch of her body.

Jihoon bared his teeth as rough moans kept escaping his lips.

Even though he’d marked her snow-white body with red traces everywhere like blossoms of heat, it still felt woefully insufficient.

A violent urge to chew up and devour the white woman before him kept boiling up inside him.

Just leaving bite marks on this white body wasn’t nearly enough.

A growing thirst arose alongside the ever-increasing desire to push her even more mercilessly.

“Honey, even if it hurts, just bear with it for a moment.”

“Hngh, mm…”

“I’ll, hah, make you feel really good. For the rest of your life, I’ll make you feel good…”

That day when she’d collapsed dead drunk.

Just like that day when he’d stripped her sleeping body and spread his semen all over her, drenching her in a dominant Alpha’s pheromones. Today too, he would generously spray his pheromones all over this small, delicate body.

He would make sure she could never spout nonsense again about flirting or dating other bastards.

As Jihoon pushed his thick, long middle finger into Sia’s tight entrance, he vowed he wouldn’t go easy on her anymore.

“Hah, ngh…!”

“Hah, Sia, relax.”

Sia’s inner walls were warmer and more clingy than he’d imagined.

Even with just a finger inside her, the overwhelming sense of connection washed over him like a wave.

“Jihoon, ngh, it feels weird, hah…”

“It’s because you’re too tight. Relax. Otherwise you’ll get hurt.”

Jihoon coaxed and soothed his adorable omega, who was squirming her hips and shedding tears at the unfamiliar intrusion, as he pushed in another finger.

Jihoon’s large hands, with each finger having an extra joint compared to most men, were nearly twice the size of Sia’s tiny ones.

Her tight entrance, which had never even taken something as thin as a cotton swab, struggled to accept Jihoon’s finger, which was noticeably thicker and more substantial than the average man’s.

“Sia, you need to relax. Okay?”

“Hngh, Jihoon, it’s weird, so weird…”

“Shh, it’s okay. It’ll feel good soon.”

Still, as expected of an omega in heat, she was so wet that there was no dryness at all.

And as Jihoon’s fingertips began to gently and persistently rub the sensitive spot inside her, a strange pleasure started spreading throughout her entire groin.

Sia, who had been twisting her hips at the unfamiliar intrusion, was soon soaked in pleasure and unconsciously lifted her hips in response to the fingers stirring her inner walls.

“Sia, does it still hurt?”

“Hah, no, mm, Jihoon… more, hah… there, ngh, hah…”

“Ha, Park Sia. You’re really… why are you such a baby? Hm?”

Looking up at him with those glistening eyes, meekly succumbing to the pleasure he gave her—Park Sia was so cute it defied description.

Even her tight hole earnestly sucking his fingers was adorable.

Jihoon pulled his fingers out from inside her, then immediately gripped his thick cock and rubbed the head against her entrance.

His cock, veins bulging even more than before, was swollen as if it might burst at any moment.

As his hot cock rubbed against her tight entrance, another gush of slick arousal poured out from deep inside Sia.

“Sia, I really… hah, I’ll make you feel so good. I promise…”

Jihoon gripped her hips tightly and slowly pushed himself into her still-tight hole.

“Ngh, mm…!”

“Ha… it feels so good, Sia.”

A sensation far more ecstatic than when he’d used his fingers enveloped his entire cock.

The warm inner walls gripping him tight, the soft flesh rubbing against his balls, the endless flow of slick arousal—everything about Sia was unbearably ecstatic and pleasurable.

Just from being inside her, he felt like he could come at any moment.

“Hah, Sia.”

“Jihoon, slow, ngh, ah, ahh!”

Jihoon pushed himself deep inside, all the way to the spot where Sia felt it, and then began thrusting roughly.

“Ha, Park Sia, it feels so fucking good.”

“You’re, you’re too deep, ngh… I can’t, I can’t… ah!”

The violent thrusting of his hips continued with slapping sounds.

Jihoon looked down at Sia, her whole body trembling, struggling, with his cock still buried inside her, and rubbed her small, protruding clit.

His dark red cock plunged in and out, attacking her inner walls. At the same time, he rubbed her clit like crazy, sending a tingling sensation through her like an electric current, making her entire groin throb.

The intense pleasure that felt like it would melt her made moans burst out mindlessly from between Sia’s lips.

“Jihoon, not, there, ah, ngh, ah…!”

“Ha, as if you don’t like it. You’re fucking dripping.”

As her clit and inner walls were stimulated simultaneously, Sia writhed desperately, unable to bear it.

Not only was her most sensitive spot being relentlessly stimulated, but her clit was being mercilessly teased as well—intense pleasure surged from her toes to the crown of her head like a tidal wave, washing over her small body again and again.

Her mind kept going completely blank.

“Ngh, Jihoon, it’s too much, too much, hng, haa…”

Unable to withstand the intense stimulation any longer, tears began streaming down from Sia’s large eyes.

Watching Sia bite her lips tightly as tears rolled down her cheeks, Jihoon swallowed hard.

He felt torn between wanting to hold this tiny woman preciously and cherish her tenderly, and a sadistic urge to push her relentlessly and make her a mess.

If he could, he wanted to tie up this small body and suck and lick every corner of her like candy all day long.

Consumed by the desire to lick up every drop of fluid flowing from her body, Jihoon pressed kisses—chu, chu—to the corners of her eyes and licked up her tears with his tongue.

“Hah, Sia, you need to breathe properly.”

“Jihoon, it feels weird, hng, you, it’s too much, ngh, it feels weird… Ah, aah!”

“Fuck… You’re, hah, so fucking pretty I’m going crazy. Sia.”

Jihoon pinned her tightly in his arms and began thrusting into her even more fiercely.

With the relentless stimulation, Sia twisted her waist as tears streamed down her face.

Below her navel, a sharp tingling kept pulsing, and a swirling sensation washed over her groin again and again, making her feel like she needed to pee.

The repeated waves of intense pleasure left her so weak that even moaning became difficult.

Drenched in tears, Sia clutched Jihoon’s firm forearms with her small hands and shook helplessly like a deflated doll.

“Gasp…!”

“There, wait, ah, haah, ah, aah!”

The moment Jihoon thrust upward sharply, hitting her inner walls with a hard, sudden motion.

She felt the vivid sensation of something hot flooding into her belly.

“Hng, Jihoon, ngh…!”

“Hah, baby, just hold on a little longer.”

Jihoon held Sia even tighter as she flinched and squirmed, trying to pull away from him, and rubbed his cock even deeper inside her as if to squeeze out every last drop.

“Haah, hah…”

Jihoon covered her with gentle kisses as she lay sprawled out without the strength to move a finger, then slowly withdrew his cock halfway.

Milky white fluid trickled down from where their genitals were joined.

“W-wait. Jihoon… hng…!”

Jihoon licked his lips, as if regretting the loss of the semen spilling from her, then gripped her slender waist tightly and thrust his still-hard cock deep inside her once more.

Jihoon rubbed his cock against her inner walls, still hypersensitive from the climax she’d just reached, and continued his second round of thrusting.

“I, hng, it’s too much, it’s too much, hnngh, ngh…!”

“Hah, Sia, it feels so good…”

“Hnngh, Jihoon, hah… I, I can’t…”

With no time to rest, his hips started moving again, and Sia gripped Jihoon tightly with her small hands, sobbing and wailing.

“You’re beautiful, Sia.”

“S-slow down, hng…!”

“So beautiful, Sia.”

Jihoon gazed at the small omega flushed red with eyes that seemed lost in ecstasy.

Her eyes and nose tip reddened from crying so hard, her plump lips gasping for breath, her perky breasts bouncing mercilessly up and down… all of it was unbearably stimulating.

Thinking that he, in his right mind, seemed to have lost his reason more than Park Sia in her heat cycle, Jihoon pounded the spot that made her feel good with hard, relentless thrusts.

The lewd squelching sound of their flesh slapping together echoed through the cramped room.

“Fuck, Park Sia, you’re so fucking hot.”

“Hngh, Jihoon, hah, ngh…!”

“Sia, hah, I wish I could show you where we’re connected too.”

Jihoon gazed at the foam created by his cum mixed with Sia’s juices, letting out ragged breaths.

“Jihoon, hah…!”

Unable to withstand the pleasure, Sia instinctively flailed her small hands like soft paws, and her kitten-like appearance made Jihoon’s cock swell even harder with renewed vigor.

How many countless nights had he jerked off while recalling Park Sia’s expression as she glared at him fiercely like a wildcat?

Fantasizing about her crumpled face eventually flushed with pleasure, and in the end, clinging to him while sobbing uncontrollably—getting off to those delusions had become one of Jihoon’s indispensable daily routines.

“Fuck, what did you eat to get this cute?”

“Hah, ngh…!”

“Park Sia, why are you so cute? Hm?”

Jihoon took Sia’s small hand flailing in the air into his mouth, frantically licking her small, white hand and showering it with kisses.

Then, gripping her voluptuous breasts bouncing up and down with both large hands, he sucked on them frantically like a nursing infant.

He teased the tip of her hardened nipple with his pointed tongue, then sucked in her entire areola as if nursing.

But why was it?

Even as he kneaded her fair, smooth skin like dough and left bite marks, his thirst only grew.

It still wasn’t nearly enough.

“Hah, Sia…!”

“Jihoon, there, ngh, haah, ah, ahng!”

They both climaxed simultaneously.

Jihoon pulled her trembling body close as she shook from the intense orgasm, once again frantically showering Sia’s face with kisses.

“Mmph, mm…”

“Hah, you’re so cute, Sia.”

Even though her clumsy makeup, drenched in sweat, had become a complete mess, her fresh face looked exceptionally pretty.

Without withdrawing his member, Jihoon fondled her soft cheeks and flushed ears, once again nibbled and played with her skin.

Sia, who had been twisting her hips from the pressure she still felt inside, suddenly fainted in Jihoon’s arms from the intense wave of relaxation.

“Park Sia, I think your body’s too weak.”

Jihoon gazed at her sleeping soundly like a child in his arms with a look of absolute adoration, gently brushing her sweat-soaked long hair behind her ear.

“I wish you’d hurry up and get pregnant with my baby.”

Jihoon murmured darkly, caressing her slightly protruding, flat stomach.

“Mm…”

Had she somehow sensed his low murmur? Sia, sleeping in Jihoon’s arms, made a soft sound and twisted her body.

“Hah, fuck. You’re such a damn baby.”

The sight was once again so adorable that Jihoon’s heart swelled.

Her babyish cuteness made his nose prickle with emotion.

An overwhelming feeling that he could do anything for her, whatever it might be, bloomed uncontrollably within him.

“How the hell are you this cute… Sia, yeah?”

Jihoon fiddled with her small hand, then showered her tiny hand with kisses for a long time.

Because he had already bitten and sucked on them several times, Sia’s fingers were thoroughly soaked with Jihoon’s saliva.

He rubbed his nose against her neat, small nails that weren’t even manicured, then bit each of her ten fingers one by one and left teeth marks on the back of her hand.

“Really, hah, you’re the cutest in the whole world, Sia…”

Only after he had mouthed and nibbled at her skin to his satisfaction did Jihoon reluctantly withdraw his cock.

Having ejaculated twice, an even greater amount of semen gushed out from Sia’s hole than before.

Jihoon repeatedly pushed the flowing semen back inside her with his fingers, then gazed down at the soundly sleeping Sia.

Holding Sia as she slept peacefully in his arms, he felt that none of the time or effort he’d spent turning her—a beta—into an omega had been wasted.

It wouldn’t be an exaggeration to say he’d lived his entire life just to feel the ecstasy of this very moment.

Yet still, Jihoon felt something was lacking.

“Sorry, but I need something more definitive.”

Jihoon smiled softly as he caressed Sia’s pale nape.

He had begun moving in earnest toward this day right after hearing the news that Park Sia had been accepted to the same S University as him.

Sia, who didn’t get along well with her parents and disliked being at home, had constantly talked throughout her exam prep years about how she’d start living on her own once she got accepted.

It seemed her parents had promised to cover at least the security deposit if she got into her desired university.

When she actually got accepted, Jihoon found himself worrying about Park Sia starting to live alone more than he felt joy about attending the same university.

In Jihoon’s eyes, Park Sia was the cutest and most adorable creature in the world.

Sia was lovely and beautiful even bare-faced, but once she started wearing makeup and dressing up in earnest, it was obvious she’d attract even more vermin than she already did.

In fact, despite her cute appearance, Sia’s easygoing personality meant she’d always gotten along well with male students throughout elementary, middle, and high school. Whenever the boys held popularity polls, Sia consistently ranked near the top.

Throughout their school years, Jihoon had secretly intervened whenever a guy tried to approach Sia with romantic intentions.

However, unlike in high school where their routes and acquaintances completely overlapped, it was no longer easy for their daily lives to intersect since they were in different majors at university.

Even after starting university, it was virtually impossible to monitor Sia’s every move.

Just the thought of Park Sia renting a cramped room near campus and inviting other men over to joke around and hang out would make Jihoon get heated at all hours. He grew increasingly anxious.

Jihoon asked his cousin—a doctor who specialized in trait research—to make time for him, and over dinner, he asked him directly.

He’d once heard at a family gathering that his cousin had a few patients who were definitely betas whose traits changed to omegas.

“I’m asking out of personal curiosity, but is there a way to turn a beta into an omega? Artificially, I mean.”

“Hmm… it’s not impossible. But that’s only possible if you’re dominant.”

“So a dominant Alpha like me could turn someone who’s a beta into an omega?”

“Dominant Alpha pheromones are toxic, you know. If someone’s exposed to that toxicity severely for a very long time, their trait can change. For omegas, their heat cycles can get completely thrown off, and even Alphas might stop going into rut.”

Kang Jihoon—who was always forced to attend family gatherings with dead fish eyes—not only took the initiative to ask to meet his cousin, but also bombarded him with relentless questions, so his cousin answered reluctantly.

“Jihoon, dominant toxicity is worse for you more than anyone else… So stop thinking about other things and hurry up and find a decent omega to bond with. If you don’t properly release your pheromones, they’ll keep building up in your body and cause problems. You might not notice it now while you’re young, but you’ll feel it more and more as you get older.”

He was actually asking for an artificial way to turn a beta into an omega? Unbelievable.

His head was already starting to throb, wondering what kind of awful thing his cousin sitting across from him was about to do.

“Enough with the lecture—just tell me a concrete way to turn a beta into an omega.”

When Jihoon completely ignored his cousin’s advice, his cousin let out a faint sigh and answered.

“If someone is continuously exposed to dominant pheromones for a long time in a very small room, wouldn’t that work…? Usually, when you look at cases where someone’s trait suddenly changed, it was often when they were forced by a dominant Alpha in rut in a very small room. Saliva and semen especially contain a lot of pheromones.”

“But wouldn’t doing that put the other person in danger? Because of the dominant Alpha toxicity.”

“Mm… If you’re worried about the toxicity, you could bond with them… When the pheromones are bound, all the accumulated toxicity is purified.”

“Bonding purifies the toxicity?”

“Yeah. When you imprint and bond with someone, the Alpha and omega’s pheromones bind together, and all the toxicity accumulated in both the dominant Alpha and omega completely disappears. When the pheromones bind, their constitutions change so that neither can have any negative effect on the other. So even a dominant Alpha with toxicity can have safe sex with their bonded partner.”

“Ah. So that’s… what imprinting is…”

“Right. Plus, once the pheromones bind, from that moment on, Alphas and omegas can’t smell any scent other than their partner’s pheromones. That’s why you need to be really careful about who you bond with. It’s absolutely irreversible.”

Even with his cousin’s worried tone, Jihoon’s heart couldn’t help but race.

Just imagining Park Sia becoming his mate, responding only to his pheromones—it was enough to make his lower body ache.

He’d heard a bit about Alphas and omegas pairing up and imprinting during sex ed, but after Sia manifested as a beta, Jihoon’s interest in bonding with omegas had dropped off sharply, so he’d just let all that talk wash over him.

But now, the idea that bonding would tie their pheromones together—that kind of fate kept making his heart race uncontrollably.

‘That’s so fucking romantic…’

To have his pheromones bound with Park Sia, now manifested as an omega. To never be able to smell anyone else’s scent again. For all of it to be absolutely irreversible.

An act like an eternal shackle, making it so neither of them could ever look at anyone else for the rest of their lives—Jihoon found it unbearably romantic.

But he felt anxious not knowing the exact details—how much pheromone exposure was needed, how long he’d have to keep doing it.

What if, while he was putting in all that effort, some other bastard snatched Park Sia away?

Remembering the ordeal of secretly dealing with the betas and Alphas who’d approached her during their school days, Jihoon looked sideways at his cousin.

“Isn’t there a way to increase the odds? I need a surefire way.”

Watching Jihoon, who wasn’t even trying to hide his intentions, his cousin let out a heavy sigh as if he had a headache.

At least among Jihoon’s family, there wasn’t a single person who didn’t know he’d been harboring a one-sided crush on his childhood friend Park Sia for ages.

Even Jihoon’s mother had privately expressed her disappointment when Sia was classified as a beta.

“If you want to increase the odds, you need to lower their immune system. If they’ve got the flu or COVID, or if they’re run down from drinking too much and their stamina’s shot, the probability goes up. If someone who’s been exposed to dominant pheromones for a long time gets thoroughly drenched in dominant pheromones while their immune system is weakened, that’d do the trick, right?”

“The most potent pheromones would be… semen?”

As Jihoon muttered in a low, sinister voice, his cousin furrowed his brow and snapped at him, as if he couldn’t take it anymore.

“Kang Jihoon. Do you really have to go that far?”

“What?”

“You’re doing this because you want to change Sia’s classification. She’s living happily as a beta right now, and you’re trying to change her just because you want to—“

“If it’s not her, I can’t do it. I decided that from the very beginning.”

Jihoon cut off his cousin’s attempt at a lecture and answered.

“You’re an Alpha too, so you know. If you don’t bond with the person who first gets stuck in your heart, you’ll be miserable for life. If it’s not her, I don’t even get turned on. I can’t even get it up. She comes at me like she wants to kill me every time she sees me… I don’t know why it has to be her. I’m so frustrated I’m going crazy.”

From the day he first fell for Park Sia, he’d decided that she was his mate, no matter what her classification turned out to be.

The Alpha instinct—once they find someone they like, they can’t give up until they make that person their mate—only intensified after Jihoon was classified as a dominant Alpha.

He became increasingly, almost pathologically curious about Sia’s every move.

Whenever those sparkling, pretty eyes followed someone other than him, his chest ached as if it were being torn to shreds.

For the first time, he learned that loving someone too much could hurt—hurt enough to be agonizing.

Those few short weeks after starting college, when he’d used free periods as an excuse to come and go from Sia’s apartment, were the happiest moments of Jihoon’s entire life.

Was it because being alone with her in that cramped space made him dizzyingly giddy and happy? Unlike in high school, he felt like the distance between him and Sia had closed a little.

In fact, Sia—who used to growl at him like she wanted to devour him whenever she saw him—had actually mellowed out, and she no longer showed her dislike for him the way she used to.

‘Even without forcibly changing her secondary gender… could I maybe even date Park Sia, a beta?’

Maybe, by gradually getting closer like this, they could naturally become lovers…

Throughout his comings and goings at Sia’s place, Jihoon held onto hope that if things continued this way, the two of them might naturally start a relationship like any other couple. Her attitude had softened considerably compared to before, and he nursed this vain hope all by himself.

At least, until a new contaminant named Junik appeared.

“While we’re on the subject, you probably shouldn’t come over to my place anymore. I won’t order delivery from you either.”

“What? Why? Didn’t we already have an agreement?”

“The guy I’m about to see told me I smell like an Alpha and asked if I was dating someone. Just how comfortable are you making yourself at my place that you’re leaving your pheromones all over me like this? Do you have to sabotage my marriage prospects?”

The day Park Sia suddenly told him not to come to her place anymore, Jihoon was consumed by an unbearable sense of betrayal and sorrow, his anger rising to the top of his head.

Once again, it felt like he’d been the only one excited and happy, and his pride was wounded.

He’d paid a fair price all this time for using her place, and he’d even recorded their agreement. He was irritated with Park Sia for turning their promise into nothing more than a blank sheet of paper just because of some new guy who’d shown up.

It was an absurd situation where the newcomer was trying to push out the one who’d been there first.

As a precaution, Jihoon had been exchanging contact information and building connections with upperclassmen and underclassmen in the Korean Literature department behind Park Sia’s back. He quickly reached out to Sia’s group project members and made certain deals with them.

All of Sia’s group members, who desperately needed networking connections in the job market more than their immediate grades, readily accepted Jihoon’s offer to introduce them to people he knew. After all, there wasn’t a single person around Sia who didn’t know that Jihoon was the grandson of K Group.

The sudden ruin of the group project, and Sia getting completely wasted afterward—all of it was, of course, part of Jihoon’s plan.

What’s more, Sia had already been exposed to Jihoon’s pheromones throughout the entire semester as he came and went from her studio apartment, killing time. Her body was filled to the brim with the pheromones of the dominant Alpha.

“Hey, Park Sia. You brought this on yourself, you know?”

Even if Sia had been left alone, it wouldn’t have been strange for her to eventually transform into an omega.

“I was being considerate, trying to take it slow, but you kept provoking me… so I had no choice, right?”

He could never forget the look on his cousin’s face—ashen as he told him that Sia’s traits had changed to recessive omega—when he carried Sia, completely drenched in extremely dominant pheromones, to his cousin’s hospital.

The moment he faced his cousin’s twisted expression, looking at him as if he were some kind of monster, bells of euphoria rang out in his head.

But that wasn’t the end of it.

[Mr. Junik, I’m sorry. I’ve decided to seriously date a friend I’ve liked for a long time… I don’t think I’ll be able to contact you separately anymore. I’m sorry.]

While she was asleep, Jihoon used her phone to send a message to Junik, pretending to be Sia.

After sending the message saying she’d started seriously dating someone she’d liked for a long time and asking him to stop contacting her, he cleared their entire chat history.

‘Seriously, Park Sia has weird taste too. What’s so great about this idiot-looking guy?’

Jihoon checked Junik’s profile picture and let out a scornful laugh, as if he couldn’t believe it.

‘Is she some kind of nerd collector or what? Why does every guy she’s into look like this?’

The man—much smaller than him, with a pale face and gentle features—wasn’t attractive to other men at all.

Jihoon couldn’t understand Park Sia at all—why was she flirting with some inferior recessive Alpha when she had him, a dominant Alpha, right in front of her?

‘Should I just destroy her phone…?’

For a moment, a dark impulse rose within him to throw Sia’s phone out the window and break it, but Jihoon calmed himself and slowly combed through her phone’s contents.

Only after spending several hours checking all the conversations she had exchanged, one by one, did Jihoon finally place her phone carefully back inside Sia’s tote bag, as if nothing had happened.

He didn’t care if the whole world thought he was a crazy bastard.

As long as Sia stayed by his side, he didn’t care at all if everyone pointed fingers at him and insulted him.

The only person Jihoon wanted in this world was Park Sia.

“If I leave things as they are, Park Sia will definitely run away…”

The media whispered about eternal love, often showing romantic scenes of Alphas and omegas who, after promising marriage, marked each other.

Every time Jihoon saw ideal Alpha-omega couples on TV, he felt a surge of murky emotions rise up inside him.

What was ordinary reality for others was like an unreachable fantasy for Jihoon.

Dating like normal Alpha-omega couples, promising love, having sex, marking each other…

Of course, there had been moments when he’d dreamed of such scenes. But to dream of such an ending with Park Sia, who didn’t see him as a romantic prospect at all, it would be quicker to just be reborn.

“I’ll make you happy for the rest of your life, Sia.”

Jihoon laughed softly as he showered the sleeping Sia with gentle kisses.

The moonlight settling over her snow-white naked body seemed as elegant as a wedding dress, he thought.

Vowing to dress her in the most glamorous and expensive dress in the world at their wedding, which would come in the not-too-distant future, Jihoon slowly brought his face closer to her snow-white neck.

“I love you, Sia.”

Jihoon pledged his eternal love to the adorable omega sleeping soundly in his arms, then bit down hard on her soft, downy, snow-white nape.

The moment his teeth sank into her supple, apricot-scented skin, their pheromones surged powerfully from the spot where their bodies touched.

As Sia’s pheromones spread through every cell of his body, Jihoon felt his heart burn with heat.

It was like falling deeply in love—as if clear bells were ringing in his ears.

The intensity filled his chest to bursting, and he felt tears threatening to spill over.

Though invisible to the eye, he could feel it clearly—Sia’s powerful pheromones wrapping around his body like chains.

The pheromones of a dominant Alpha and omega, binding them together beautifully as they enveloped the two…

“Hah… Sia.”

Jihoon gazed at the vivid Alpha mark now etched on her snow-white nape, his face lost in ecstasy.

This badge of honor, like an eternal, unbreakable promise, would bind the two of them together for life.

From now on, she would never sense another Alpha’s pheromones. And no other Alpha would ever sense hers.

He caressed her white nape with satisfaction, then showered ticklish kisses over the mark he’d left once again.

“Park Sia, I’ll make you happy for the rest of your life.”

It didn’t matter if Park Sia, upon waking and discovering he’d marked her, came to hate him all over again.

“So please, just stay by my side. Please…”

Now that Sia had been marked by Jihoon, there was absolutely no way for her to escape him—at least not in this lifetime.

***

“Ugh…”

Sia barely managed to blink her eyelids, heavy as wet cotton, and moved her head.

Her small body shifted under the weight pressing down on her entire body, and she screamed internally when she saw Jihoon sound asleep with his mouth still latched onto her breast.

‘Gasp! Cra-crazy… What is this…!’

The moment she saw Jihoon wrapped around her body like a snake as he slept, the intense sex they’d had flashed through her mind like a panorama.

She still had a slight fever from the lingering aftereffects of her heat cycle, so she wasn’t in perfect condition. But compared to when she’d been completely intoxicated by pleasure, she was capable of rational thought now.

‘Of all people, how could I… with Kang Jihoon… Am I actually insane?!’

Sia, her small hand covering her mouth, struggled to push Jihoon away. But no matter how much she squirmed, his rock-solid body wouldn’t budge an inch.

“Hah…”

Sia pressed her temples and let out a sigh.

From the day her heat cycle suddenly started, she’d spent two full days tumbling together in debauchery with Jihoon.

The dominant pheromones filling the cramped studio apartment were so intoxicating and sweet that when she passed out and came to, they’d immediately press their lips together and tangle their tongues, without either of them needing to make the first move.

Jihoon’s cock, which had thrust in and out countless times, slid naturally into her inner walls as if finding its rightful place, and when the two became one, she’d cling to his solid body again, moaning loudly.

On the narrow single bed, on the floor, in the bathroom, in the kitchen. All day long they sucked and devoured each other’s skin. They really did roll around messily, as if leaving traces of each other in every corner of the tiny apartment.

They even continued eating with him still inside her, and did not hesitate to bury their faces in each other’s lower bodies and lick each other’s secret places, assuming even the most shameful positions.

Jihoon even smeared the complimentary whipped cream that came with the delivered bread all over Sia’s breasts and pussy before licking it off.

Sia, thoroughly aroused by Jihoon’s caresses, also got swept up in his pace, licking the whipped cream slathered thickly on his hard shaft and balls along with the cum that hadn’t been wiped away yet.

Not only that, but Sia herself spread her legs and urged Jihoon.

Touch me, suck me, put it in—she didn’t hesitate to use dirty words as she pleaded for his penetration and ground her hips against him as if pressing herself tightly against him.

She’d even grabbed both her swollen breasts and put them directly into Jihoon’s mouth herself. As these shameless scenes came back to her one by one, Sia’s entire body trembled with intense humiliation.

‘Did some disgrace star enter my fortune this year?! How could I do such, such things…!’

The situation was already mortifying enough just from having rolled around mindlessly with Kang Jihoon of all people, but when the memory of her lewd self begging him for caresses and penetration surfaced, she truly wanted to bury her face in a dish of water and die.

Heat cycle or not, how could she have lost her reason so completely and chased after nothing but pleasure? Thinking back on those two days when she hadn’t been herself, goosebumps kept rising all over her body.

But unlike Sia, who was shocked and confused, Jihoon slept peacefully, like a baby.

His smooth lips—the ones that usually only spouted annoying remarks—were pressed firmly shut as he slept. Jihoon had a face that was, though she didn’t want to admit it, sculpted and handsome from every angle.

After barely managing to move his large, rock-like, unmoving body off herself, Sia clutched her head with both small hands.

‘Ugh… How am I supposed to face Kang Jihoon now?’

She lowered her head to look at her body, covered all over with bite marks.

The breasts Jihoon had been sucking on just moments ago were swollen and puffy, and her vulva, red and swollen from having taken him inside her so many times, also stung and ached.

Maybe it was because they’d spent two whole days doing nothing but filthy things.

Even the lightest brush of her own skin sent shivers of strange sensation rippling through her like heat haze.

The feeling of his thick, hot tongue licking her kept coming back to life, and before she knew it, slick arousal fluid gushed out from her narrow opening.

‘Shit, what did I even do to be dripping like this…?’

Seeing the arousal fluid trickling down even though she wasn’t doing anything, Sia turned pale and clamped her hand over her mouth.

Afraid even the slightest sound might escape, she pressed her small hand tightly over her lips, then carefully crawled out of bed.

‘I can’t take it anymore because of Kang Jihoon’s pheromones.’

Sia bit down hard on her lip at the dominant Alpha pheromones still filling the room.

The fear that if she kept breathing in this scent, she might clench tight again and lose her reason completely gripped her suddenly.

If Jihoon were to wake up in this state, if she kissed him again and breathed in those powerful pheromones he was giving off…

She was terrified that she’d spread her legs for him and offer up her body like someone under an irresistible spell, completely entranced.

‘I need to get out of the house. There’s no way I can think straight here.’

Sia hastily threw on whatever clothes she could find, grabbed only her phone, and rushed out of the house.

Outside, the sun hadn’t risen yet—it was still the dim light of early dawn.

Breathing in the clear air free of Jihoon’s pheromones, she finally felt the fog that had clouded her mind begin to lift somewhat.

Now that her senses had fully returned, her head was filled with only one thought: she needed to take emergency contraception as soon as possible.

There was no way an omega in heat and an Alpha intoxicated by that omega’s pheromones would have bothered with proper contraception. Moreover, no matter how hard she tried to recall, not a single fragment of memory surfaced of Jihoon putting on a condom—which meant they’d definitely gone at it raw and frenzied.

But it was still far too early in the morning, and all the pharmacy doors were firmly shut.

She searched for 24-hour pharmacies where she could buy contraceptives, only to feel utterly defeated when she saw the notice stating that omega-specific contraceptives could only be purchased with an ID confirming omega status.

‘Ugh… Maybe I should’ve just registered my ID after all. Who knew there’d be this kind of inconvenience.’

That was when it happened.

As Sia stood dazed in the middle of the alley, a group of burly men, arms slung over each other’s shoulders, came stumbling toward her—clearly drunk.

‘Oh god, are they Alphas?!’

The men were tall and heavily built, as if they’d majored in physical education—unmistakably Alphas at first glance.

Terrified, Sia instinctively shrank back.

But the Alphas walking toward her paid her no mind whatsoever, simply continuing their chatter.

Of course—not every Alpha would be interested in every omega. She’d been overthinking it.

Just as that embarrassing thought crossed her mind, Sia sensed something strange.

‘Inside that bathroom when my heat cycle hit, I could smell the pheromones of the Alphas outside… so why can’t I smell those men’s pheromones?’

Sia pressed her small hand to her temple, trying to recall the day her heat cycle had struck.

She distinctly remembered the scent of the Alphas who had been outside the bathroom.

Unlike Jihoon’s pleasant, cool pheromones, theirs had been so strangely foul and pungent that she’d had to cover her nose.

But today, even though she wasn’t wearing a mask, she couldn’t smell any Alpha pheromones at all.

‘Wait, did I turn back into a beta?’

Sia, who had briefly swelled with hope, suddenly had a prickly feeling that something was wrong.

If her traits had suddenly reverted to beta, there would be no way to explain the lingering, hazy aftereffects of her heat cycle.

Though her mind had fully returned, she still felt feverish as if intoxicated by something, and the insides of her thighs itched.

Most importantly, the faint sweet apricot scent wafting from her body still proved she was an omega.

“Ha, I don’t know. I need to get some birth control pills first.”

But now wasn’t the time to think about all these things.

No matter how low the pregnancy chances were for a recessive omega, after having such intense sex with a dominant Alpha during her heat cycle, the possibility of pregnancy couldn’t be completely ruled out.

Sia trembled as she recalled Kang Jihoon ejaculating inside her over and over, refusing to let her go.

The fact that she’d lost her reason and slept with him because of her heat cycle was already enough to make her head spin—but if she got pregnant with his child on top of that…

That would be absolutely insane.

Everything up until now could be written off as a two-night mistake, but the moment she had his child, she might end up in a truly irreversible relationship with the guy friend she despised most in the world.

He wouldn’t want that any more than she would.

Sia hurriedly ducked into a nearby 24-hour franchise café.

Then she called Yeseo, her friend since elementary school who was also an omega.

— Hey, Park Sia. What time do you think it is? Why are you calling? Is something wrong?

As soon as the call connected, Yeseo’s groggy voice came through the phone, still thick with sleep.

“Sorry, Yeseo. You’re the only person I could call…”

— What’s going on? Nothing’s seriously wrong, is it? Where are you? Are you home?

It was the first time Sia, who normally kept boundaries even with close friends, had suddenly called at such an early hour. Worried that something serious might have happened to her friend, Yeseo’s voice became more serious.

“Well… do you happen to have any contraceptives?”

— What kind of contraceptives?

“Omega contraceptives.”

— I do have some I bought as a backup. But why would you need contraceptives? You don’t even have a boyfriend.

“Ha… I don’t have a boyfriend, but I think I screwed up.”

Sia covered the phone with her hand and answered in a small voice, worried someone might overhear this embarrassing conversation.

— Park Sia! Did you finally lose your V-card? But why contraceptives? If you’re a beta, it wouldn’t matter.

“No, well… you’re right, but actually, I… my trait changed…”

— Your trait changed? To what?

“…Omega. Recessive omega.”

— What?!

Sia let out a sigh and honestly confessed everything that had happened to Yeseo.

How she’d ruined her group project and ended up drinking heavily even though she normally didn’t drink at all, how she’d passed out cold, how she’d woken to the earth-shattering news that she’d transformed into an omega, and finally, how her heat cycle had suddenly hit and she’d ended up sleeping with Jihoon…

Yeseo was so stunned by the rapid-fire revelations that she couldn’t find words to respond. Into the silence, Sia added in a worried voice:

“But something’s weird. I can’t smell other Alphas’ pheromones.”

— What do you mean?

“I could definitely smell Kang Jihoon’s pheromones back at my place, right? But when I saw other Alphas on the street, I couldn’t smell anything. Is that normal?”

— Um… normally you don’t sense Alphas’ pheromones as strongly as during a heat cycle… it’s more like a faint scent. But the thing is… your heat isn’t completely over yet, is it?

At her question, Yeseo asked back in a troubled voice.

“I don’t think so. I still have a fever and I’m not feeling completely back to normal.”

— Wait. Did Kang Jihoon bite your neck at any point?

“Bite me?”

— I’m asking if Jihoon left any bite marks around your neck.

In that instant, Yeseo raised her voice, realizing the gravity of the situation.

“Well… it’s really embarrassing to say this out loud, but he was sucking on me everywhere…”

— No, not that. I mean a real bite mark from him biting down hard. It looks completely different from just sucking. It leaves a mark like a deep indentation.

“Hmm, hold on.”

To Yeseo’s somewhat urgent question, Sia apathetically looked at her reflection in the café window.

Perhaps from being worn out by Jihoon for two days straight, her face looked more haggard and listless than usual.

She casually checked her forearms and the area around her legs.

Everywhere she looked, the reddish marks left behind were embarrassingly like mosquito bites.

Kang Jihoon really was like a dog, biting and sucking on her body all day long.

He’d left marks all over her body with relentless persistence, so of course there were a couple on her neck.

She hadn’t looked closely, but there were probably marks he’d left even on the most intimate parts of her inner thighs.

“Haah… I don’t know. All I really remember is clinging to him and begging over and over… Yeseo. Why did I do that?”

Every time she checked each mark on her body, memories of clinging to Jihoon and moaning uncontrollably kept coming back.

Had she ever felt this much self-loathing in her life? Had she ever been this humiliated?

Sia let out a heavy sigh, as if she might collapse, and buried her head on the café table.

“I never imagined I’d lose control of myself like that. I really…”

— Listen carefully and don’t freak out. I think… Kang Jihoon might have imprinted you.

“Imprinted?”

— Are there any other Alphas at the café right now?

At Yeseo’s question, she glanced at the café part-timer who was clearly an Alpha and a male student studying all night on his laptop in the corner.

“There are, but I can’t sense any pheromones from them at all. It’s like I’ve become a beta again.”

— Omegas can sense Alpha pheromones even when they’re not in heat. It might not be as strong or intense as during heat, but they can still tell what kind of scent an Alpha has. But you’re at the end of your cycle, and you’re saying you can’t smell anything from other Alphas? The only explanation is… your pheromones and Kang Jihoon’s are bound together.

“Pheromones bound together? What does that mean?”

— Sia. Hang up right now and use your phone to take a picture of the nape of your neck. Hurry.

When Yeseo, who was usually playful, kept speaking so seriously, Sia realized how serious things were and quickly hung up.

Then she picked up her phone and tried her best to take a picture of the nape of her neck.

‘Ugh, this is way harder than I thought.’

But she couldn’t exactly grab strangers and ask them to take a picture of her neck either.

After several attempts, Sia finally succeeded, and a chill ran down her spine when she discovered the bite mark clearly visible on her pale nape.

‘…What the hell. It really does look a bit different from the other bite marks…’

She pulled down her t-shirt slightly to compare the bite marks on her collarbone with the mark in the photo.

The deep, vivid bite mark carved into her skin looked distinctly different from all the other marks covering her body—even to someone like her who knew little about Alpha-omega imprinting, it was clearly suspicious.

Finally snapping to her senses as if doused with cold water, Sia turned pale and sent the photo to Yeseo.

— Holy shit. Kang Jihoon imprinted on you?

The moment she sent the photo, Yeseo called her.

“…What?”

— I was right earlier. I think you got imprinted by Kang Jihoon and your pheromones are bound. Sia, what are you going to do… You can’t respond to any pheromones except Kang Jihoon’s now. Same goes for him, though…

“Wh-what does that mean?”

— What do you mean what? It means you can’t sleep with any other Alpha now, not in a million years.

“What?! What are you talking about?”

— You have to have sex with only Kang Jihoon for the rest of your life, you idiot!

“That’s insane! This can’t be happening!”

The moment Sia heard Yeseo’s words—a curse declaring she could never have sex with any man but Kang Jihoon for the rest of her life—she screamed like Munch’s The Scream.

Sia also, of course, knew about imprinting.

When Alphas and omegas who love each other leave a mark as a token of their pledge of eternity and become mates.

An unbreakable promise shared between Alphas and omegas who have pledged eternity and promised to marry.

It was a happiness only those born as Alphas and omegas could enjoy, but also a shackle that bound them together.

Though she’d lived her whole life as a beta, she knew from various media just how weighty becoming mates and forming an imprint bond was.

That made it even harder for Sia to understand Kang Jihoon.

Why on earth had he done this to her?

Why would a promiscuous, dominant Alpha do that? Why, of all things?

No matter how much she racked her brain, she just couldn’t make sense of Kang Jihoon’s actions.

— Why? Is he bad at it? Is his dick small? He didn’t seem like the type…

After a long silence on the other end of the phone, Yeseo continued in a worried voice.

— Still, with a face like Jihoon’s, even if it’s small, wouldn’t it be forgivable…? I mean, he’s that good-looking—if he was hung too, that’d be overkill. Plus, there are plenty of good toys these days…

No. It was big. Really big. But that’s not the problem!

Sia barely swallowed the words that had risen to the tip of her tongue, realizing Yeseo had misunderstood—she thought Sia was upset because Jihoon’s dick was small and the sex unsatisfying.

Even though Yeseo was a close friend, the three of them had been elementary school classmates. They knew each other’s faces and family situations inside and out, but somehow Sia didn’t feel like discussing every little detail of her time in bed with Jihoon.

‘Ah… I’m suddenly feeling dizzy.’

Suddenly overwhelmed by a great shock, Sia felt dizzy and sank down on the spot without realizing it.

“Yeseo. I’m really not feeling well. I think I have a fever.”

— If your heat cycle hit two days ago, you’re right in the middle of it now. You probably burned through a lot of pheromones rolling around with Kang Jihoon, but… even so, it’s dangerous to be wandering around outside like this.

Yeseo nagged her omega friend who was still acting like she was a beta.

— Stop spacing out and get home right now. When my heat cycle hits, I don’t leave the house at all for a whole week, even with suppressants. If you’re unlucky, something dangerous could happen.

“Who’d be interested in me? I don’t even give off pheromones anymore.”

— No, seriously, there are some real freaks out there, okay? There are psychos who specifically target imprinted omegas. Since you can still get pregnant with other Alphas, you always have to be careful!

Yeseo’s nagging continued, but Sia brushed off her friend’s advice dismissively.

It was the same on the street, but none of the Alphas in the café seemed interested in her either.

People who manifested as omegas naturally attracted Alphas’ attention more than betas who gave off no scent, thanks to their distinctive pheromones. But here she was, safe even wandering around outside during her heat cycle. The situation was no different from when she’d been a beta.

“Yeseo. If I go home like this, I feel like Kang Jihoon’s going to devour me again. If this goes any further… I might actually end up in the hospital!”

That’s when it happened.

The scentless café suddenly filled with a cool, deep woody fragrance.

For a moment, it felt as if a dark, deep forest had suddenly unfolded before her.

— Park Sia, then come to my place for now. Do you have money for a taxi?

“Yeah. Send me your address. I’ll grab a taxi right now and…”

The moment Sia reflexively shrank back at the all-too-familiar pheromones, a large hand reached out and snatched her phone away.

“K-Kang Jihoon!”

“Yeseo. It’s Jihoon. How’ve you been?”

Jihoon, having snatched the phone and startling Sia, looked down at her coldly. In a chilly voice, he spoke to Yeseo.

“You heard everything from Park Sia just now, right? She’s mine now. So from now on, if you want to have a long call with her, get my permission first.”

As soon as he finished speaking, Jihoon abruptly hung up. Sia, suddenly angry, clenched her small hands into tight fists.

“Are you insane? Who the hell do you think you are, hanging up on someone else’s call? And why am I yours?”

“In the middle of the night, where do you think you’re going, sneaking off in a taxi like a little rat?”

Jihoon, his mood clearly sour, moved even closer, his gaze dark and shadowed.

“It’s not the middle of the night… it’s dawn…”

“Why? Planning to eat and dump me?”

“What? Eat and dump?”

“Eat and dump, right? You were running around in heat, spreading your pheromones to seduce me, and now you’re trying to act like nothing happened and run off to Yeseo’s place.”

Under Jihoon’s relentless barrage, Sia found herself at a complete loss for words.

“When did I ever seduce you?! And since we’re on the subject, you said you imprinted on me. What the hell is this? What are you trying to do? Are you seriously insane?”

“How is that my fault? You’re the one who didn’t take suppressants and went around in heat. That’s why this whole mess happened.”

“What?”

As if not using proper protection wasn’t bad enough, he even went and imprinted on her as he pleased. How dare he act so self-righteous?

Sia was so flabbergasted by Jihoon’s shameless audacity that she pressed her small hands to her temples and replied.

“Jihoon, we need to talk.”

“Talk, my ass. Don’t make me angrier. Just get in my car.”

“No, let’s talk here. I have something to say to you.”

Though Jihoon looked genuinely angry—unlike his usual smug demeanor—and it frightened her, Sia bit down hard on her lip and glared at him with all her might.

She already felt wronged enough for having been swept along and given herself to him in a daze—she didn’t want to meekly follow his orders and get in his car.

Watching Sia’s feeble resistance, Jihoon let out a scoff and swept his gaze across the café.

Unfortunately for her, there was nothing about Sia that Jihoon didn’t know.

Having observed her every move from close by for so long, he knew all too well what situations she feared and wanted to avoid most.

“Park Sia. Should I say out loud everything that happened between us in front of all these people?”

“…What?”

“Where should I start? Maybe with Park Sia, the Korean Lit beta who turned into an omega, wandering around campus in the middle of her heat without even taking her suppressants properly? Oh, or how about the fact that you were kindly told you needed to update your ID after your secondary gender changed, but you lied and kept pretending to be a beta? You know you can get fined for that, right? If you got exposed on Eta, that would be quite a show.”

As Jihoon mocked her, picking apart each of her wrongdoings, Sia’s face went blank with shock.

Did she really have a choice here?

When she froze up, unable to say a word, Jihoon grabbed her thin wrist and strode out of the café.

He put her in the passenger seat of his car parked outside, quickly locked the door, and stepped on the gas.

Glancing at Sia sitting quietly in the passenger seat, looking completely defeated, an unbearable anger rose up inside him.

“Do you hate me that much?”

He roughly turned the steering wheel, trying to calm the rage that had risen to the top of his head.

“…What?”

“No, I’m just getting more pissed off the more I think about it. You spent two whole days crying and moaning with my cock in your mouth, and then the second you got a little better, you just ditched me and ran away.”

As Jihoon growled low, Sia shrank back, pressing her lips tightly together and avoiding his gaze.

Early that morning, the moment he opened his eyes and realized Park Sia had disappeared, Jihoon had been furious to the top of his head, but he calmly got dressed and quickly ran out of the cramped studio apartment.

An omega in heat cycle inevitably gave off pheromones far more intense than usual.

Following the trail of her pheromones, it wasn’t difficult to find the café where she was hiding.

In fact, even without the pheromones, Park Sia was within his grasp.

But even after catching her, going back to Park Sia’s place again would be no different from giving her another chance to escape.

Jihoon immediately took his car, which he’d parked near the school’s back gate, and went to the café.

Sure enough, Park Sia was on the phone with Choi Yeseo—her best friend and also Jihoon’s elementary school classmate—tearfully recounting every detail of what had happened.

The moment he saw her looking like her world had collapsed at the fact that she’d been imprinted, Jihoon felt his own heart plummet to the floor.

Of course, he knew full well that she pushed him away, that she didn’t like him romantically.

No, he was actually well aware that she hated him quite intensely.

But after countless times of their bodies intertwining, sharing kisses, their pheromones mixing together—he’d hoped that maybe, just maybe, some of that hatred toward him would have diluted and faded away…

He’d expected that once they became mates, like toxins accumulated in the body being purified, her heart would also naturally, magically bloom toward him…

As if shattering that sliver of hope, the moment he saw Park Sia agonizing over how to escape him, rage surged all the way to the top of his head.

“Kang Jihoon. Let’s not do this. We’ve known each other for over ten years… This doesn’t make sense.”

After staring anxiously at the scenery rapidly passing by the car window for a while, Sia spoke with difficulty.

“I’ll take responsibility.”

“What?”

“I’ll take responsibility for you. This oppa can handle that much, Sia.”

At Jihoon’s sudden words, Sia looked at him with startled, rabbit-like eyes and demanded an explanation.

“Have you completely lost your mind? What, are you saying you’ll marry me or something? Are you insane? Do you think that makes any sense?”

“Why wouldn’t us getting married make sense?”

Seeing her jump in shock, Jihoon growled.

“Kang Jihoon. How can you think it makes sense for you and me to get married? No, we’re not even dating in the first place.”

“You spread your legs and shook your hips asking me to fuck you, and now you’re acting like a stranger? Even you know that doesn’t make sense, right?”

“No, that was because of my heat cycle, I couldn’t help… Mmph…!”

The moment the light turned red, Jihoon grabbed her small face tightly and pulled her toward him. Then he bit down on her lips that rejected him and roughly shoved his tongue inside.

“Mmph, ngh, mm…!”

As his tongue entered through her parted lips and his saliva flowed in, she could once again strongly feel Jihoon’s thick, cool pheromones at the tip of her nose.

It was strange.

The moment she caught his pheromones, she couldn’t move, as if bound by invisible chains, and kept heating up.

“Haa, ha… ngh…”

And the resolve that had been screaming no just moments ago melted away like snow, while a primal instinct to touch him more slowly welled up.

“Strange, isn’t it?”

“Hng…”

“When you smell my pheromones, you get so fucking turned on you can’t stand it, right? You want me to fuck you, don’t you?”

Jihoon smirked as he watched the small omega become so aroused from just a kiss that she didn’t know what to do with herself.

“That’s why you need to marry me.”

The light turned green again.

In the passenger seat beside him, Park Sia let out gentle, purring breaths, aroused from their kiss moments ago.

Her sweet pheromones pouring out made Jihoon feel like he was losing his mind.

Driven by the singular thought of getting home as quickly as possible to become one with his omega, he pressed harder on the accelerator.

The touching from earlier had left Jihoon’s lower half in a bad state.

If he could, he wanted to drag her into any available space right now and roll around with her wantonly.

“Little Joraeng.”

Jihoon reached out with his right hand and firmly grabbed her pussy.

“It’s only been a few hours since I last saw you, but—ha—I already want to see your pussy.”

“Wait, Jihoon… Ah…”

“Let me touch your hole. Spread your legs properly for me. Hm?”

Taking advantage of the red light, Jihoon roughly shoved his hand inside her loose shorts and panties.

Park Sia, who would normally have pushed him away sharply, was too intoxicated by the rising heat cycle to push him away forcefully, and could only twist her hips.

“W-we’re outside. Ngh, what if someone sees…?”

“Don’t worry. My car’s tinted really well.”

As the light turned green, he kept driving while kneading her soaking wet pussy with his right hand.

When he slipped his fingers between her folds and rubbed, Sia moved on her own, bucking her hips in rhythm with his touch.

Watching Park Sia obediently accept his touch without resisting made his crotch swell even more menacingly.

The squelching sound of his fingers rubbing against her pussy echoed lewdly inside the car.

“Fuck, you took my cock for two whole days straight, so how is your hole still this tight?”

Jihoon pressed his index and middle fingers firmly against her tight hole, breathing roughly.

As he rubbed her entrance in circular motions, another gush of slick fluid poured out from inside Sia’s tight opening.

“Sia, why is everything about you so small… it’s cute.”

“Hngh, mm…”

“Never thought I’d see the day I’d be driving while fingering Park Sia’s pussy. I’m so honored I could die.”

The soft texture of her pubic hair against his hand, the scorching heat of her sex, the slippery wetness, his omega’s pheromones filling the car… everything was unbearably stimulating.

Jihoon licked his lips and glanced at the passenger seat.

It was almost tragic that he couldn’t properly watch Park Sia rub herself against his hand because he had to keep his eyes on the road.

“Babe, pull down your pants and panties.”

“Why, hah, should I, babe…”

“Hurry up. I can’t finger your pussy properly otherwise.”

In the confined space, as their pheromones tangled together, an even more intense arousal swept over them than when they’d had sex in the studio apartment.

Sia lifted her hips, helping Jihoon as he pulled down her pants and panties.

Any rational thought about how they shouldn’t be doing this had long since flown away.

Once her pants and panties were off, her lower body was instantly exposed to the air.

“Spread your legs wider. Yeah?”

“Hah, mm, yeah…”

Already soaked in pleasure, Sia obediently spread her legs wide in an M-shape as Jihoon instructed and accepted his touch.

The warmth of his large hand kneading her entire pussy felt unbelievably good, and before she knew it, Sia grabbed his wrist and started rubbing her pussy herself.

“Ha, babe. Feels good?”

“Mm, yeah… feels good.”

“You like it this much, but you ran away first thing this morning?”

As if punishing her, Jihoon slapped her pussy a few times, then pinched her clit.

“Haah, mm, there, hnn…!”

“My baby, you like it when I touch you here, don’t you? Hm?”

“Mm, I like it, yeah, hah… Jihoon, ah…!”

This time, as he massaged her small, protruding clit in circles with his index finger, Sia bucked her hips and trembled all over.

At that adorable reaction, he rubbed her clit even faster, and her tight hole flowed endlessly.

“Jihoon, haah, ah, ngh, ah!”

As Jihoon rubbed her clit at a maddening pace, an orgasm suddenly swept through her like a tidal wave, spiraling from the tips of her toes all the way to the crown of her head.

The lewd sensation, so different from penetration, made Sia grind her pussy against the large hand touching it, letting out muffled moans.

“Hnn, Jihoon, mm…”

“Want me to touch you more?”

“Hah, yeah, mm… more, more… it’s not enough, hnn…”

“Ha, fuck. I can’t hold back either.”

The moment Sia, having completely lost her reason, urged him to put it in, Jihoon let out a rough metallic sound and turned the steering wheel sharply.

There wasn’t an Alpha in the world who could possibly hold back when the omega he loved most gripped his hand and begged for him to put it in.

He turned the wheel and pulled onto the Dulle-gil Trail* walking path where he went running every morning.

[*T/N: Hiking path in Seoul. This originally said Olle Trail but that’s in Jeju Island but the latter sentence mentions Seoul so I changed it.]

Since it was a jogging trail, the air was fresh, and if you climbed high enough, you could see a panoramic view of downtown Seoul.

Because it was early dawn, Jihoon roughly parked the car in an empty lot beside the Dulle-gil Trail, where there were no people except for the occasional runner.

Then, after reclining the passenger seat, he climbed on top of Sia.

The moment he mounted her, Sia, drunk on arousal, spread her legs on her own and her tight hole puckered eagerly.

“My Sia. Are you begging me to put my cock in your pussy?”

“Jihoon, hah, yeah… put it in… mm…”

“Fuck, you’re so damn cute, seriously… I’m going crazy.”

Jihoon, his voice rough with desire, gazed at Sia, who was begging for his cock, and showered her adorable face with kisses.

Sia, whimpering and moaning with her legs spread wide, was so unbearably adorable that he felt like he could come right then and there.

“Sia. But remember what I taught you to say at times like this? Hmm?”

“Hah, uh, what was it…?”

“You need to politely say, ‘Honey, please put your cock in my pussy,’ right?”

Jihoon gripped his dark red, vein-bulging cock and rubbed it against the narrow hole dripping with slick fluid.

When he only teased her entrance with his tip without putting it in, Sia pleaded with him in a desperate voice.

“Jihoon, hah, please…”

“Say ‘honey,’ hah, say it properly. Hmm?”

Jihoon rolled up Sia’s shirt, then pulled up her bra and pinched her nipples.

Her nipples, swollen from him sucking and licking them all day, hardened at the slightest touch.

As Jihoon teased her by rubbing her pussy and breasts at the same time, Sia whimpered, unable to hold back any longer, and parted her lips.

“Hah, in, in Sia’s pussy…”

At her cheeky yet adorable display, Jihoon gave a gentle, encouraging smile and tickled her chin with his fingers.

“H-honey… ngh, your cock… please put it in.”

“That’s right.”

As if rewarding his obedient, lovely omega, Jihoon pushed his thick cockhead past her entrance and into her.

“Hah, ngh, ah!”

“Hah, Sia, ah…”

The hole that had held him all night gaped around him, swallowing him eagerly, as if it was already used to him.

“Jihoon, ah, there, it, it feels good, ah…!”

As her small hands and feet clung tightly to Jihoon’s large body, the wet sound of their bodies slapping together filled the air as he thrust into her hard.

Already knowing exactly where she was most sensitive, Jihoon focused his thrusts on those spots, moving his hips at a maddening pace.

Sex in the studio apartment and sex in the car each had a different vibe.

Just thinking about taking her to different places to make love in the future made his already fully hard cock swell with even more strength.

“Doing it in a tight space like this is, hah, fucking hot, isn’t it?”

As Sia bounced her hips in rhythm with Jihoon’s thrusts, she grabbed his large hand soaked in her arousal and pressed it against her breast.

The sight of her begging him to touch her tits was unbearably arousing, so Jihoon kneaded her pale breasts like rice cake and asked.

“You like it when I suck on your tits?”

“Ngh, yes.”

“I wish milk would come out of here soon… hah, Sia.”

Jihoon peppered her overwhelmingly lovely lips with kisses.

“When you get pregnant, your nipples will get bigger and darker too.”

He licked Sia’s still-small nipples with his tongue, murmuring as if enraptured.

“I can’t wait to see it. Your body changing because of me.”

“Hngh, Jihoon, it’s, it’s so deep, hah…!”

“Sweet. You’re so sweet, Park Sia.”

“Hah, ngh, mmm…!”

Jihoon showered Sia’s lips with kisses as he mercilessly rubbed against the spot where she felt it most with his hot cock.

“When I’m with you, hah, I love you so much… that I, I keep losing myself.”

“Jihoon, there, haah, ah, ah!”

They climaxed at the same time.

Their bodies went limp with languid relaxation, but without either of them taking the lead, they clung to each other and once again shared a kiss, their tongues tangling and intertwining.

“Mmph, mmm…”

“Haah, hah…”

Each other’s pheromones were so sweet, so intoxicating.

Without a stitch of clothing between them, the two embraced each other’s bodies and explored one another like people who had lost all reason in the cramped confines of the car.
