The Main Character is Obsessed With a Foreign Substance

Seunghyun couldn’t track Suhwan’s location through his phone. So he called someone else. It was Lee Taehyun, his father and the former owner of HS. While he actually needed to speak with his mother, she didn’t have a personal phone, so he had no choice but to contact his father. It didn’t matter much since they would be together anyway.

Kim Suyeon, Seunghyun’s mother, had been frail since childhood. Her family was known for producing many omegas, and among her already weak omega sisters, she was particularly sickly and frequented hospitals. Her family worried she might not even live to adulthood.

Fortunately, she grew up well until she became an adult, but her family began to worry in a different way. Kim Suyeon, with her beautiful appearance and fragility, attracted alphas’ attention just by existing. Not just alphas, but betas too were captivated and followed her around.

Concerned, Kim Suyeon’s family gave her a gift—a bracelet with a tracking chip embedded in it. The simple silver bracelet had such a basic design that it wasn’t worth stealing, and it was so thin that kidnappers wouldn’t suspect it contained a chip, making it easy to deceive their eyes.

The tracking information was initially held by Kim Suyeon’s father, and after marriage, it was entrusted to her husband, Lee Taehyun. Years later, Kim Suyeon gave the bracelet to her youngest son, who resembled her exactly. Now, Kim Suyeon knew the bracelet’s tracking information.

“It’s me, Father. I’d like to speak with Mother briefly.”

—…

His parents were momentarily flustered by their youngest son’s sudden call after such a long time. But seeing Seunghyun’s urgency, they promised to text him the bracelet’s tracking information.

After ending the call, Seunghyun returned to the laboratory. Jaehyun felt puzzled seeing Seunghyun’s cold expression.

“What? Did something happen?”

“Hyung.”

“Yes?”

Jaehyun unconsciously flinched at Seunghyun’s serious demeanor. Looking at him, Seunghyun said in a grave tone:

“Don’t leave the lab until I contact you.”

“What?”

“If you must go somewhere, make sure the guards accompany you.”

“Hey!”

Then he quickly turned, took off his lab coat, and gathered his things. Ignoring Jaehyun’s calls, he immediately left the laboratory. Jaehyun stared after him with an incredulous expression.

After returning home, Seunghyun entered his room and retrieved a black bag hidden deep inside. His eyes darkened as he examined the items within.

The items he took out were quite sinister: a stun gun for self-defense, pepper spray, rope, and electrical tape.

These were enough to easily dispose of a person. Ironically, these were originally self-defense items he’d acquired to protect himself. But having never needed to use them, they’d been forgotten in a corner until this urgent situation reminded him of their existence.

Buzz.

“…”

A message arrived with a small vibration. Seunghyun checked his phone. After confirming the address, he picked up the bag and got up.

***

“Ju Geonyul.”

“…”

“I clearly warned you.”

“…!”

Dressed in black from head to toe, Seunghyun looked like a grim reaper who had just risen from hell. Geonyul startled when he approached.

Fuck, he cursed inwardly, frowning. How pathetic to be frightened by a mere omega again. Geonyul gritted his teeth and got up.

Seunghyun’s gaze turned to Suhwan lying on the floor. He was unconscious in the chaotic room. The bright red handprints on his neck, as if he had been strangled again, were the first things noticeable. Then Seunghyun took in every detail: the tear-stained face, one swollen red cheek, the bare upper body with fresh marks, and bruises with traces of blood.

“You… really want to die, don’t you?”

“Ugh…!”

Finally, Seunghyun’s gaze turned to Geonyul. His eyes were filled with murderous intent and rage. At the same time, his fierce pheromones pressed down on Geonyul.

It was unbelievable. How did he know this location, and how did he get past the guards stationed outside? As Geonyul looked at Seunghyun in disbelief, his eyes widened when he spotted the silver bracelet rolling at his feet.

“Ha, you’re quite out of your mind too, Lee Seunghyun.”

“…”

“Does Suhwan hyung know your true self?”

Seunghyun didn’t even blink at the mocking words. He had always known his actions weren’t normal. But what could he do? Seunghyun stared at Geonyul with cold eyes.

“Shut up.”

“Kuk.”

Pheromones stabbed at his entire body with deadly intent. It was an aura filled with killing intent incomparable to before. Geonyul sensed danger through instinct. The omega before him genuinely wanted to kill him.

“I have no reason to spare you. Right?”

“W-wait!”

Seunghyun found it difficult to contain his rising anger. He had no intention of forgiving Geonyul for daring to touch what was his. Though worried about Suhwan’s condition, it was actually fortunate that he was unconscious. If he woke up and saw Seunghyun, he would surely be terrified. While controlling his pheromones to prevent them from reaching Suhwan, Seunghyun slowly approached Geonyul.

“Fuck, don’t come any closer!”

Geonyul was in panic. His pheromones fluctuated unstably. Subduing him now would be as easy as twisting a child’s wrist.

But it wouldn’t be fun to subdue him so easily. Even returning the pain Suhwan suffered many times over wouldn’t be enough. Seunghyun picked up a liquor bottle that had fallen at his feet.

Crack!

“Argh…!”

The bottle smashed into countless pieces as it struck Geonyul’s head. Blood dripped steadily from his bowed head. A beast-like howl erupted from his mouth. Seunghyun looked down at him with an emotionless face.

“Wait, w-wait! I said wait!”

“I told you to shut up.”

Seunghyun frowned at Geonyul, who was still noisy despite his cracked head. In his hand, he held a half-broken bottle. The sharp glass shards, protruding like knife blades, gleamed in the light. With a calm expression, Seunghyun raised the broken bottle again.

Yes, kill him. Let’s kill him right here. Eliminate him so that he can never approach Suhwan again, never do such filthy things again. As Seunghyun was resolving this with cold eyes…

“…!”

Wee-oo, the sharp sound of sirens was heard from afar. And it grew louder as it approached. Seunghyun turned his head in surprise.

“They’re here already.”

It was Seunghyun who had alerted the police in advance for any possible situation. He had called them to rescue Suhwan in case he couldn’t handle it himself, but they had arrived earlier than expected.

“…Lucky bastard.”

Perhaps due to his alpha dominant trait’s sensitivity to pheromones or from the shock of mortal fear, Geonyul had fainted. Seunghyun irritably threw aside the bottle in his hand and turned away from the unconscious Geonyul.

“Hyung.”

“…Ugh.”

“Haa.”

A faint moan escaped from Suhwan as Seunghyun gently caressed his cheek. He was just unconscious. Seunghyun sighed in relief.

“I’m sorry for being late.”

“Hn…”

“I’ll see you later.”

After kissing one of Suhwan’s cheeks, Seunghyun stood up. He needed to erase any traces of his presence before the police arrived. Seunghyun examined the shackles restraining Suhwan’s arms, twisted the loosened joint, and broke the chain. Then he repositioned the liquor bottle.

If Hwalyeon found out that he had rescued Suhwan, she would feel uncomfortable. Seunghyun was aware that tracking and following one’s fiancé wasn’t normal behavior. So he couldn’t let anyone find out. Not even Suhwan.

‘Does Suhwan hyung know your true self?’

“…”

At that moment, Geonyul’s voice echoed in his ear. For some reason, that unpleasant voice wouldn’t easily leave his mind. As Seunghyun frowned, he finally turned away when the siren sound came very close.

***

Suhwan only opened his eyes the next day. Waking up in a hospital room, he discovered Seunghyun hunched over, tightly holding his hand, and spoke:

“Seung… ugh.”

Other parts were fine, but his face was so swollen from being hit hard that it was difficult to speak. He closed his mouth, feeling extreme pain after trying to call Seunghyun’s name. But even at that small sound, Seunghyun noticed instantly and opened his eyes.

“Hyung, are you okay?”

“Yes.”
