The Main Character is Obsessed With a Foreign Substance

2.

His head was filled with the scent of fruit. A citrus fragrance that Suhwan loved so much he couldn’t resist. The pheromones that had thoroughly saturated his brain led Suhwan’s body helplessly forward.

“Mmh.”

His mouth was completely filled with something. Something soft yet firm slid across Suhwan’s tongue. Suhwan couldn’t hold back a moan. In response, the pressure binding his tongue grew stronger.

“Ah!”

With a wet sound, warm liquid flowed down the back of Suhwan’s throat. Suhwan unconsciously gulped down that sweet liquid. Then whatever was filling his mouth pushed deeper, threatening to block his throat completely.

“Uh, nnh.”

Struggling, Suhwan’s hands clutched tightly at the collar of whoever was pinning him down. Not in his right mind, Suhwan couldn’t understand what was happening. He just thought hazily: It feels good. I’m going crazy. Do more.

Thinking this, he gripped the person’s collar even tighter. In response, the other person embraced Suhwan so firmly it felt like he might crumble.

“Ah, hah.”

Who’s making these pleasurable moans? Suhwan wondered vaguely, feeling a tingling in one corner of his mind. When Suhwan hesitated for a moment, the tongue filling his mouth chided him by rubbing intensely against the roof of his mouth. Finding it difficult to breathe, Suhwan twisted his head while opening his mouth wide.

“Hah, S… Seung…”

“Haah, what is it?”

Only then did Seunghyun slowly separate his lips and look at Suhwan with heated eyes. Hearing his voice, Suhwan blinked stupidly before finally beginning to register what was before him.

Seunghyun’s eyes had darkened considerably. Unlike the morning when even the dust floating around him seemed to shine, now his eyes looked as fierce as those of a beast.

“W-wait.”

How did this happen? He couldn’t understand why he was kissing the main omega like this. When the confused Suhwan came to his senses and tried to push him away, Seunghyun’s hand gripped Suhwan’s nape and pulled him up sharply.

“No.”

“Hnngh!”

Once again their lips locked perfectly. A moist tongue parted Suhwan’s lips, entered, and licked his teeth and every corner of his mouth. Having no experience with this, Suhwan found it challenging just to receive his tongue.

It was true what they said about all omega bodily fluids tasting sweet to alphas. The saliva coming from Seunghyun seemed to contain concentrated fragrance. It was overwhelming enough with the intense kiss, but with the sweet scent continuing to invade his mind, it was unbearable.

“Mmnn, nnh.”

“Ha, why, like this…”

Even while sucking on Suhwan’s lips and tongue like an animal, Seunghyun occasionally muttered words that contained confusion, as if he couldn’t understand his own actions. He now held Suhwan’s face with both hands, continuing the passionate kiss.

At first, it was clearly Suhwan who started it. He had raised his head first and kissed Seunghyun. At that time, Seunghyun had worn a smirk, thinking things were going according to his plan. He was certain that Suhwan, entranced by his pheromones, would reveal his true nature and act violently toward him.

But all Suhwan did was a bird kiss, barely brushing their lips together. It was a feather-light kiss that even elementary school kids these days probably wouldn’t do. And even after doing that, Suhwan’s face turned red as if embarrassed.

What is this…?

Surprised by the unexpected behavior, Seunghyun frowned at the subtle fragrance tickling his nose. He faintly detected a sweet and cozy scent like baby powder. Seunghyun soon realized this was pheromone coming from the alpha beneath him.

Until now, Seunghyun had never smelled the recessive alpha’s pheromones. Perhaps due to Jin Suhwan’s inferiority complex about him being a dominant omega, despite all their interactions, he had never released his scent. Seunghyun had once imagined that his pheromones would smell terribly.

But this unexpectedly soft fragrance? Shocked, Seunghyun’s body stiffened. And when he faced that slightly flushed face, he felt something snap in his mind.

When he came to his senses, Seunghyun found himself kissing Suhwan like crazy. He was rubbing his lips against the lips of the person he had hated so much until now, moaning like a beast.

“S-Seunghyun, ah, stop.”

“Haah, ha.”

The hands pushing him away didn’t seem to have much strength. So Seunghyun didn’t take the command to stop at face value. Surely the other must be feeling as good as he was, with a corner of his mind melting. Certain of this, Seunghyun held Suhwan’s cheeks and gently bit the tip of his tongue.

“Ah!”

Suhwan’s eyes widened as the sharp pain shot through his bitten tongue. However, even that pain felt like intense pleasure. Despite it being his own body, it felt like it didn’t belong to him. He wondered if his entire body was going to melt into a puddle.

But when Seunghyun’s knee pushed between his legs, Suhwan snapped back to his senses as if cold water had been thrown on him. With surprising strength, Suhwan shoved Seunghyun away.

“Ugh!”

“Huh?”

Pushed by Suhwan’s arms, Seunghyun was momentarily forced to the edge of the bed and sat down, his eyes wide open. Even that surprised face was terribly beautiful. Just as the fiercely terrifying expression had suited him, how far did this main omega’s charm extend?

Suhwan clutched his still-pounding chest and jumped up from his seat.

“S-sorry!”

“Wait…”

Before Seunghyun could grab him, Suhwan quickly left the bed. Then he opened the door and exited the bedroom.

Click.

With the door closing behind him, Suhwan ran like mad. But since they were in the same house, there was nowhere to escape where Seunghyun couldn’t follow, so he entered Jin Suhwan’s room and locked the door.

“Huff, hah.”

Leaning against the locked door, he gasped for breath. His pounding heart was so loud it made his ears ache.

“Phew.”

When there was no sign of anyone approaching from behind, Suhwan finally relaxed and let out a long breath. Then he covered his reddened face with both hands.

They say alphas and omegas are beasts. When swept away by lust, reason collapses in an instant. Suhwan had viewed the relationship between alphas and omegas too lightly. If this was happening on the first day, how was he supposed to endure a month…?

“…Huh?”

Suhwan, consumed by self-loathing, suddenly opened his eyes wide. Seunghyun had told him to prove his innocence without laying a finger on him. But already… hadn’t they crossed the line?

Suhwan’s face turned pale as he blinked. To cling to each other like beasts after just one day—it was the worst. So now was the engagement cancellation off the table…?

Suhwan’s face tilted to the side. Focused only on getting Seunghyun’s permission, he hadn’t thought about what would happen next. What if they couldn’t break off the engagement? Would they have to continue it? But Seunghyun probably wouldn’t want that either.

“Ugh, my head hurts.”

With his thoughts becoming more complicated, Suhwan shook his head vigorously. Then he approached the chair-like sofa where he had dozed off in the afternoon. He was planning to stay here for a while, then take a blanket and sleep on the living room sofa. Suhwan crouched down on the chair and nodded his head like a sick chicken.

Click.

The bedroom door closed, and the sound of footsteps gradually faded away. Only then did the light return to Seunghyun’s previously hazy eyes.

‘What on earth did I do…?’

Like someone else, Seunghyun covered his face with one hand, feeling self-disgust. His golden-brown eyes, visible between thick fingers that were large for an omega, were deeply furrowed.

Nothing was going according to his intentions. Jin Suhwan, whom he had met after a month, had become too strange. That face full of filthy desires had only been disgusting, but now the face that blushed shyly after a bird kiss looked cute. A large alpha being cute!

“Haah.”

Seunghyun lowered his head and gazed at his center with a troubled expression. It wasn’t strange for an omega to be excited by an alpha’s pheromones, but the impulse he felt when he noticed his erection confused him.

Jin Suhwan was an alpha, and he was an omega, so why?

Why would he want to put this inside him…?

“I’m going crazy.”

Shaking his head, Seunghyun fanned himself as if trying to cool down. Closing his eyes, he began carefully counting down from 10,000, subtracting by 7s. As he recited these numbers, his arousal gradually subsided.

It seemed he shouldn’t encounter him for a while. At this rate, instead of carrying out his plan, he might be the first to cross the line due to strange impulses.

Seunghyun raised his eyes and scanned the corner of the bedroom. A small, invisible camera would still be running. He didn’t even want to check how he and Suhwan had been captured just now.

“Huff.”

Turning his eyes away, Seunghyun crawled on his knees to the center of the bed and closed his eyes. Perhaps because someone else had been there until just now, the bed suddenly felt too large to sleep in alone.

***

All weekend, Seunghyun had gone somewhere, leaving in the morning and not returning home. Suhwan, who had been afraid of running into him, ordered delivery food again for himself on Sunday evening and returned to his room.

That awkward kiss… he felt like he should talk about it, but he couldn’t since he couldn’t meet the person involved.

Maybe Seunghyun wanted to just move past it? That seemed unlikely.

Tilting his head, Suhwan picked up the phone he had thrown on the desk. Opening the calendar, he saw some September schedules scattered throughout.

“Come to think of it, classes start tomorrow.”

Suhwan attended the same university as Seunghyun. Of course, they were in different departments. Suhwan was in Business Administration, and Seunghyun was in Pharmaceutical Sciences. Their only connection was the same club. But since Suhwan would graduate after half a semester, he had no intention of showing his face there, so the probability of running into Seunghyun at the university was almost zero.
