Taming the Obsessive Attachment

“You… you’re trying to lick my… my eyeballs, aren’t you…?”

“Ah. You caught me.”

“You son of a bitch…”

“Am I a son of a bitch? Or just a puppy?”

Seo Eui-woo mimicked a bark, “Woof, woof.”

Kwon Jae-jin felt a headache coming on.

‘How the hell am I supposed to turn that… that beast back into a human?’

Fucking hell. The curse slipped out on its own.

Even knowing that he would ultimately win in the end, the process was so goddamn miserable that he couldn’t help but swear. His vision suddenly darkened as if he were about to faint.

“Eyeballs, mucous membranes, ugh, I hate it. Guh… If you’re gonna be a mutt, then act like one and just lick my damn mouth instead.”

Jae-jin clenched his eyes shut. Then, he slightly parted his lips.

The mouth that had been tightly shut, holding back the pain, finally opened, revealing a slightly reddened tongue glistening with a thin layer of saliva. His neatly aligned white teeth were also visible. Seo Eui-woo clicked his tongue in disappointment, but he wasn’t about to refuse a meal served on a silver platter.

“Alright. I like that.”

As if he’d been waiting for this moment, Seo Eui-woo pressed his lips firmly against Kwon Jae-jin’s.

Tilting his head to deepen the contact, he plunged his tongue inside, sucking greedily without restraint. Every time he adjusted the angle of the kiss, his sharply defined jawline became even more prominent, falling into place without a single flaw.

“Mm, huugh… agh…!”

“Haa, good, mmh, so good.”

Their heated breaths collided and mixed, growing rougher.

Seo Eui-woo seemed intent on not allowing him a single moment to breathe.

His tongue, invading every inch of Jae-jin’s mouth, relentlessly rubbed against the most sensitive spots. Meanwhile, the cock buried deep inside him, like a merciless weapon, pounded against his inner walls without pause. It felt like his insides were going to rupture completely. His lower abdomen throbbed as if blood had pooled into a deep bruise.

Just as Jae-jin felt his consciousness teetering on the edge from the overwhelming assault, Seo Eui-woo reached out and wrapped his fingers around Jae-jin’s throat.

Still entangled in the deep kiss, he whispered in a muffled voice, words slurring together.

“Sleep tight, Jae-jin.”

“Then, I’ll put you to sleep now.”

At those words—ones he’d heard before, like a déjà vu—Jae-jin was violently strangled. The blood flow to his brain was cut off, and his vision gradually blurred.

The realization that he was being subjected to this nightmarish ordeal yet again sent a sharp pain through the back of his head. But there was nothing he could do about it.

“Hah, agh…! Ugh…”

A wave of dizziness washed over him as the strength drained from his entire body. The hands that had been desperately clutching at the sheets twitched and then went still.

After what felt both like an instant and an eternity of hesitation, Jae-jin slowly raised his trembling arms. Wrapping them around Seo Eui-woo’s back, he slid his fingers into the tangled strands of his hair.

At first, he roughly grabbed the sweat-drenched locks in frustration—

Then, just slightly, he stroked them.

‘Seo Eui-woo, you fucking bastard…’

He did all this—

And yet he remembered nothing…

‘He really, till the very end, is going to…’

***

When Jae-jin came to, his throat felt as if it had been scraped raw, like he’d swallowed iron dust. His lips stung and tasted of bitter, metallic blood—he didn’t even know when they had split open.

“…Ugh.”

To think that this cracked and broken voice was actually coming from his own mouth.

His body was wrecked.

Every muscle ached, his skin was covered in bruises, and blood-mixed cum trickled down his thighs. On top of that, he had no idea what day it was or even what time it might be.

Even after passing out, he had remained impaled for a long time. He had come to his senses multiple times, only to be pinned down again, his body still being pounded into. Each time, his throat was squeezed all over again.

If an emergency summons order hadn’t been issued for Seo Eui-woo, he’d probably still be getting fucked even now.

“Kuuhh…”

Jae-jin forced his weakened muscles to move.

He could barely lift a finger, but lying there motionless wasn’t an option. He groped blindly along the bedside, his fingers finally brushing against something small and flat.

A Healing Factor.

Inside the transparent casing was a vial of vivid blue liquid.

Jae-jin pulled it into his palm and twisted off the cap. A needle was embedded inside. He found a prominent blue vein on his arm, stabbed the needle in, and pressed the raised button at the tip.

The serum spread through his bloodstream, and almost immediately, his self-healing abilities skyrocketed.

His torn flesh gradually knit back together, and the dark bruises visibly faded.

For the record, this miraculous remedy was completely unknown to the general public. Most people didn’t even know the Healing Factor existed. If they did, they’d lose their minds trying to get their hands on it.

‘Or maybe… it was only nobodies like me who didn’t know about it in the first place.’

Even if they were ordinary civilians, the wealthy were probably getting their hands on it through backdoor deals.

But that wasn’t Kwon Jae-jin’s problem to worry about right now.

After injecting the entire vial of Healing Factor, he tossed the empty case aside and sank into the bed, waiting for his body to regain full sensation. His torn, filthy clothes felt disgusting against his skin, but he didn’t have the strength to take them off.

He stared blankly at the ceiling, blinking his eyes in frustration.

…It was blue.

The sky outside the bulletproof glass was a clear, vivid blue. Judging by that, it was probably midday.

The day he had been kidnapped and forcibly guided for the first time, Seo Eui-woo had returned from his combat mission around sunset. That meant there was still a fair amount of time left before he’d come back.

‘Seo Eui-woo… that bastard.’

Just thinking about him made his chest burn all over again.

Something heavy clogged his insides, like a lump stuck in his throat, making his stomach churn in irritation.

Jae-jin poured all his simmering rage into cursing Seo Eui-woo.

‘Beating the shit out of him wouldn’t even be enough… That fucking lunatic, that crazy, fucking psycho son of a bitch…’

He could accept the fact that he had regressed. That he had died. Even that he had been forced to become Seo Eui-woo’s guide for the second time.

He had even considered himself lucky to get another chance.

This time around, he could get what he wanted with less struggle. He could choose the optimal path and reach his goal without wasting time.

But, if he was being honest, deep down, he felt utterly, indescribably wronged.

Four years of effort had vanished like smoke, and the injustice of it all was driving him fucking insane.

‘That bastard—he needs to have his own fucking asshole torn apart at least once. That goddamn whore.’

Was this what it felt like to watch a painstakingly built tower crumble to dust?

The last four years of Jae-jin’s life.

All the blood, sweat, and tears he had poured into surviving had been completely wiped clean.

After enduring being kidnapped and imprisoned, after having a monster shove its dick up his ass while he painstakingly trained him, after enduring it all and keeping himself alive—he had died, just like that. A meaningless death. And all his suffering had amounted to nothing. Now, he had to start over from scratch.

How was he supposed to keep himself from losing his goddamn mind in a situation like this?

Even a saint would be driven to madness if they had to deal with this shit.

He had to take Seo Eui-woo—this fucking inhuman, monstrous S-rank Esper—and teach him everything all over again. Start from the absolute beginning, break down their fundamental differences in understanding, train him, tame him—piece by piece, from scratch.

The sheer injustice of it made Jae-jin grind his teeth so hard they ached.

What the hell had he done to deserve this? Why did he have to go through this bullshit again?

“Hah… Fuck it.”

At that moment, all the fight drained out of him.

‘Fine. It’s already happened—what the hell can I do about it?’

There was no one who would acknowledge how unfair this was. Complaining wouldn’t change a damn thing.

‘Instead of wasting time on this, I should just hurry up and train Seo Eui-woo.’

Jae-jin was alone. Completely and utterly alone.

The Seo Eui-woo who had existed in his timeline was gone.

The one standing before him now had been reset to square one.

This Seo Eui-woo wasn’t his Seo Eui-woo.

But at the same time, it wasn’t like he wasn’t his Seo Eui-woo either.

It was like a parent with Alzheimer’s—just because they lost their memories of their child didn’t mean they stopped being their parent. Similarly, just because Seo Eui-woo no longer remembered Jae-jin didn’t mean he wasn’t Seo Eui-woo anymore.

Jae-jin had already once agreed to be with him.

Therefore, Seo Eui-woo was his…

His… goddamn…

His boyfriend.

Was he his ex-boyfriend? Or still his current boyfriend? That part was a little confusing. But one thing was clear—neither of them had said the words let’s break up, so Seo Eui-woo was still his.

Boyfriend. Lover. Partner. Someone precious—whatever the hell you wanted to call it.

‘It’s not like him doing crazy shit to me is anything new… And it’s not like he does it out of malice either…’

That was why, even in his second life, Jae-jin had every intention of being in a relationship with Seo Eui-woo, just like before.

Being with him was the most convenient way to ensure his cooperation. But beyond that, somewhere deep inside, it simply felt natural that Seo Eui-woo should be his.

Jae-jin planned to tame him into something resembling a human, survive the catastrophic gate disaster that would come in four years, and then, well… after all that, he figured he’d try to live with the bastard somehow.

Maybe, with enough time, he’d start finding him endearing. Maybe he’d even grow fond of him. The constant fighting could stop, and they could just stay by each other’s side—peacefully, for a long, long time.

‘Having to go through this hell twice pisses me off, but whatever… At least I’m not some clueless newbie this time. Being a kidnapped, imprisoned veteran is still better than being a first-timer. Right?’

Besides, the hard part wouldn’t last forever.

And once it was over, the victory would be his.
