Taming the Obsessive Attachment

Seo Eui-woo chewed on the inside of his mouth, but the intrusive thoughts wouldn’t stop. It wasn’t enough to bite down on his flushed lips—he gnawed at his long, beautifully shaped fingers, yet his mind remained fixated on Kwon Jae-jin. Imagining his white thighs spread to their limit, being pounded into like an animal. Driving in so deep that bruises in the shape of his cock would be left inside those swollen, reddened walls.

A mad impulse swelled uncontrollably, to the point where he felt like he was going to lose his mind.

He found himself strange and disgusting for having such vulgar thoughts, but suppressing the urge was even harder.

‘That tight, adorable mucous membrane… Burying my raw cock deep inside, filling it up with cum, guiding… Guiding with me…’

Ugh, disgusting…

He felt like nothing more than a beast, driven purely by instinct.

Seo Eui-woo bit down hard on his fingers, the muscles tightening beneath his smooth jaw. A crease formed on the bridge of his nose, making his displeasure evident. But despite his irritation, his body reacted honestly.

His lower abdomen still throbbed, heat pooling in his core. His cock, thick and massive enough to be impossible to hide under clothing, had grown painfully hard. Seo Eui-woo’s thick eyebrows twisted violently.

‘This won’t do.’

Rather than dodging, Seo Eui-woo deliberately allowed the claws of a bat-like creature to rake across his back. The sting of the wound, the trickling of blood—it was all necessary to shake off his thoughts. He still had a long way to go before reaching the Gate’s core.

Unfortunately, Kwon Jae-jin had no idea how to use the healing factor.

No, he didn’t even know what a healing factor was.

Seo Eui-woo had made sure to leave it in the most noticeable spot on the bedside table before heading out on a mission, just so Jae-jin could use it as soon as he woke up. But when he returned, he found Kwon Jae-jin sitting on the floor, gripping a rifle, still covered in injuries—completely failing to treat himself.

“Jae-jin… Jae-jin-ssi, what are you doing there?”

Seo Eui-woo blinked a few times, his clear eyes reflecting his disbelief at the unexpected sight. From the very moment he met Kwon Jae-jin, there had been nothing but things he couldn’t understand.

“…Seo Eui-woo?”

Kwon Jae-jin was curled up in a corner of the living room, panting like a wounded animal. Clear handprints were left around his neck—evidence of having been strangled by Seo Eui-woo multiple times. The marks were horrifying. His movements were awkward, his legs trembling, his stance off-balance. Judging by how he limped, the torn flesh around his ass had likely been left untreated as well.

The only thing that seemed intact was Kwon Jae-jin’s attire. He had put back on the suit that Seo Eui-woo had stripped off him, buttoning it all the way up to his neck, appearing neat at a glance. Though upon closer inspection, both the suit and shirt were wrinkled and disheveled.

Kwon Jae-jin stared at Seo Eui-woo with wary eyes. His grip tightened momentarily around the rifle, but in the end, he couldn’t bring himself to do something as inhuman as shooting at another person. He hesitated and stopped.

“Seo Eui-woo-ssi. I am not a Guide. There is no way I could be guided, and even if I could, there must be some kind of mistake. Please return me to the Sixth Residential District.”

Upon waking up alone in the house without Seo Eui-woo, Kwon Jae-jin had naturally attempted to escape first. He searched every corner of the mansion for an exit, only to realize that every door required biometric authentication to open. He let out a frustrated sigh.

He was trapped.

Kwon Jae-jin was completely trapped.

Overcome with resentment, Jae-jin changed his approach to escape. He loaded a gun displayed in Seo Eui-woo’s dressing room and fired several rounds at the floor-to-ceiling glass windows. Of course, the bulletproof glass didn’t so much as crack.

To break that glass, one of three things had to happen: a creature had to appear, a Gate had to open, or Seo Eui-woo had to use his abilities. Empty shell casings clattered noisily as they scattered across the floor.

“Wait, hold on. Were you trying to break the window? What the hell are you doing…? Let’s get you treated first.”

Seo Eui-woo ran a hand roughly through his hair and immediately reached for the healing factor, intending to inject it into Jae-jin’s veins.

“Come here.”

“No, don’t come near me! Stop right there. Let’s talk from a distance. I said, stay back…!”

Jae-jin’s uneasy gaze fixated on the blue liquid inside the small rectangular case. Not knowing what a healing factor was, he naturally assumed Seo Eui-woo was trying to inject him with something strange. He struggled fiercely.

Jae-jin struck Seo Eui-woo’s arm with the barrel of the rifle and quickly backed into a corner of the living room. Seo Eui-woo, however, leisurely followed him with unhurried steps and pulled him into a tight embrace. He stroked Jae-jin’s back gently, as if soothing a frightened animal, comforting him in a quiet, reassuring voice.

“Ah… I should have been more careful. I must have rushed things too much… Damn, this is frustrating…”

“I don’t need it…! Just let me go.”

“Jae-jin-ssi, I’ll take good care of you. You’re my Guide now.”

Seo Eui-woo twisted off the cap of the healing factor and precisely inserted the needle into the bruised nape of Jae-jin’s neck.

Jae-jin’s face drained of color. For a moment, his eyes even reflected despair.

“What… is this? What did you just inject me with?”

Pressing a hand to the spot where the needle had pierced his skin, Jae-jin’s voice turned cold and sharp as he interrogated Seo Eui-woo.

Seo Eui-woo answered in a calm, patient tone, as if explaining to a child.

“Jae-jin-ssi, you don’t know what a healing factor is?”

“What is a healing factor?”

“You really don’t know anything. It’s a drug that enhances self-healing abilities. I left it by the bedside for you to use.”

Jae-jin’s eyes flickered with realization. He seemed to recall the blue, rectangular object that had been on the nightstand.

Seo Eui-woo gently patted and rubbed his back in a soothing manner, speaking in a quiet, coaxing voice.

“From now on, make sure to use it. You always get hurt whenever we guide.”

“…Next time?”

“By the way, I really enjoyed it… It was amazing.”

Muttering like a lovestruck boy, Seo Eui-woo cupped Jae-jin’s face in his hands, pressing their bodies even closer together as he caressed his cheek.

Backed into a corner of the living room, Kwon Jae-jin was like a rat trapped in a cage. With no room left to escape, he looked up at the shadow Seo Eui-woo cast over him, his brows furrowing in displeasure.

“My Guide… Finally… It felt so good. I’ve never experienced anything like this before. My c-chest feels like it’s about to burst. I’m so happy… What do I do?”

Seo Eui-woo smiled, his long, monolid eyes curving with amusement as he brushed his hand over Jae-jin’s cheek. His smile was innocent, his touch filled with fondness. To anyone watching, it might have seemed like he was making a heartfelt confession.

“You know, I really mean it—I’ve been thinking about you all day, Kwon Jae-jin-ssi.”

“Ugh!”

Jae-jin flinched openly, shaking his head as if trying to throw off the touch, but Seo Eui-woo was relentless. He kneaded Jae-jin’s cheeks, playfully tugged at his ears, and even went so far as to try pushing his fingers past Jae-jin’s lips.

“Let’s guide.”

“No, seriously, enough already!”

Jae-jin bit down on Seo Eui-woo’s fingers and spat them out. Then, without hesitation, he hooked his finger around the trigger of his rifle and lifted it, aiming straight at Seo Eui-woo.

“I don’t want this. I will never do that kind of thing again.”

Jae-jin growled like a cornered animal, the barrel of the gun pointed directly at Seo Eui-woo as if he were truly ready to kill him.

“I told you to send me back… I know I said it. Seo Eui-woo-ssi, if you don’t want to get hurt, let me out of here. Now.”

“No. I can’t let you go.”

Even with a gun pointed at him, Seo Eui-woo remained completely unfazed, his lips still curled into a smile. In his eyes, Jae-jin’s shallow bravado was obvious—he had never once fired at a living being in his life.

“If you do that, Jae-jin-ssi, you’ll die.”

Still smiling, Seo Eui-woo leaned in and lazily pressed a kiss against the tip of the gun’s barrel. He even let his tongue flick out, teasing the cold metal.

Immediately, an unseen force wrapped around Jae-jin’s wrist, locking it in place. His fingers, which had been gripping the rifle so tightly, began to unfurl against his will. One by one, from his pinky to his index finger, his grip was pried open. The gun slipped from his grasp and fell to the floor with a dull clunk.

Seo Eui-woo caught the rifle effortlessly with one hand and tossed it far behind him. Then, he leaned in close to Jae-jin’s ear, his voice dropping into a hushed whisper. His stormy gray eyes gleamed with dangerous intensity.

“I understand that you want to cling to an ordinary life, but you can’t go back. You’re a Guide now, Jae-jin-ssi.”

“What did you just—? Why…? My hands… they moved on their own. Seo Eui-woo-ssi, was that you?”

“Jae-jin-ssi. Do you really have no idea why this is happening? Can’t you even begin to guess?”

Seo Eui-woo released his telekinetic grip on Jae-jin’s hands, then slowly hooked his index finger under Jae-jin’s tie. He tugged it downward, gradually loosening it before unbuttoning his shirt from the top, one button at a time.

“You’re a mutant, Jae-jin-ssi.”

The abyss in Seo Eui-woo’s ever-deepening gray eyes swallowed him whole.

A pure, white-hot euphoria burned within him, consuming all reason.

“You don’t know what a mutant is, do you? It’s what they call Espers or Guides who fail to awaken at birth but suddenly manifest their abilities later in life—like you. They’re considered uncontrollable, dangerous anomalies.”

Only then did Jae-jin finally grasp the extent of Seo Eui-woo’s overwhelming power.

Even if he had a gun, it was meaningless if telekinesis could render it useless. There was no point in resisting. Against an S-Class Esper’s overwhelming abilities, struggling would only be a waste of strength.

Jae-jin decided it would be wiser to pry more information out of him instead.

With a face hardened by frustration at his own helplessness and the sheer hatred he felt for Seo Eui-woo, he lifted his chin and responded in a cold, stiff voice.
