“What the hell is going on right now?”
His voice was low—so cold it sent a chill down my spine. I thought he’d explode in anger, but the reality was the exact opposite. And somehow, that made it worse.
The silence dragged on. His piercing gaze didn’t waver, and under the weight of it, I swallowed hard, my teeth sinking into the soft flesh inside my cheek before I even realized it.
Bringing Kim Yong-ha to my Guiding Room had clearly been a mistake. I should’ve just taken him to the lounge. Of all the damn timing… why did they have to run into each other like that?
The longer we stood there in silence, the heavier the pressure from Kang Biso became. It wasn’t fear, not exactly. But the more it dragged on, the more uneasy I felt—like maybe I had done something wrong. My thoughts tangled up in a mess of guilt and frustration, and I couldn’t think straight.
In the end, I forced myself to speak.
“Um… that guy earlier, he’s just a junior of mine…”
“That bastard confessed to you, didn’t he?”
Kang Biso’s eyes were wild, like he was ready to storm out and beat the guy to death. Honestly, it was a miracle he hadn’t done it already when they crossed paths.
Truth be told, I was starting to worry about Kim Yong-ha’s safety. But even so, I didn’t want to lie. I gave a small nod.
“He… yeah. But I turned him down. I absolutely turned him down.”
“Hah. A confession? He actually confessed?”
He let out a dry laugh and stepped closer, ignoring everything I’d just said.
This moment—it felt familiar.
Right. Just like that time at the hotel. When Kang Biso had seen Baek Beom’s clothes and toothbrush and completely lost it.
But this time, his gaze was even more vicious. Like a beast ready to rip apart anything that tried to take what was his.
I didn’t look away.
I hadn’t done anything wrong. There was no reason to avoid his eyes. All the messy emotions inside me started to settle, like a storm clearing.
Back then, I’d fought back just to escape the situation. But now? I had no intention of doing that. I didn’t want to fight Kang Biso. More importantly, this time I could explain—properly.
“Listen carefully. I turned him down. And he’s just a junior at the same center. That’s it.”
Kang Biso’s brow twitched, and he tilted his head slightly—an unspoken go on.
“He’s just a junior. Nothing more.”
“There’s nothing going on between me and Kim Yong-ha.”
“……”
He didn’t say a word. His jaw was clenched tight, his expression still sharp and angry—but he did seem slightly calmer. That gave me a bit of relief. But only for a moment.
“You said the same thing to me, remember? That we were nothing.”
The words burst out of him suddenly—his voice trembling, as if he were about to cry.
“You told me we were nothing. That there was a line between us. You said that.”
“……”
“So can you really say you’re nothing with him, too? Just a junior? What if he keeps coming after you? Like I did? What then…?”
He trailed off. His chest rose sharply as he sucked in a breath, then his lips clamped shut.
I hadn’t seen this coming. Not at all.
I’d thought I was being clear. Like I told Kim Yong-ha—I only treated him kindly because I was his senior. I never expected anything from him. I just thought… since he was the protagonist, it wouldn’t hurt to be a little more familiar. That was it. Nothing more.
But hearing Kang Biso say that—it hit me like a slap to the back of the head.
I didn’t realize he’d been this upset. I didn’t even think he was misunderstanding the situation. I just thought he was mad. But this… this was something else.
And now, I actually felt bad.
While I stood there, speechless, Kang Biso let his head fall against my shoulder with a soft thud.
“Do you…”
He rubbed his head against me slightly, voice low and mumbled. I leaned in to hear him better.
“Do you think I’m not good enough for you too?”
His words were weak, quiet. But I knew exactly what had triggered them. It was what Kim Yong-ha said before he left—it must’ve stuck with him.
I spoke quickly, my guilt bubbling over.
“No. Not at all. If anything… you’re way too good for me, Kang Biso.”
He slowly lifted his head, locking eyes with me.
“……”
He didn’t say anything. Just stared into my eyes, quietly, for a long moment. Then, without warning, he grabbed the back of my neck and crashed his lips into mine.
“……Mmph.”
It was sudden. Rough. Almost violent. Our teeth collided, and pain jolted through my lips. If I was this sore, he had to be hurting too—but he didn’t care. He didn’t stop.
His lips, which had been clamped shut, slowly parted. His tongue—soft, warm, unrelenting—swept across my lips like he was savoring them. He licked, again and again, until I was soaked in his saliva. Then, like it was searching for something, it slipped between my lips.
His tongue moved with infuriating ease, twining around mine, exploring my mouth without hesitation.
“Mmmph…”
His kiss this time was slower, more deliberate than when our lips first collided. His tongue moved with unhurried ease as he wrapped his arms around my waist, pulling me in close.
As our bodies pressed flush together, I opened my eyes—and found Kang Biso already watching me.
His gaze blazed with hunger, like a predator ready to devour the prey right in front of him. There was no mistaking that look.
…But it’s strange, isn’t it?
That intense, overwhelming gaze used to make me want to recoil. But now? Just knowing he was looking at me like that sent a sharp thrill through me—enough to make my toes curl.
I didn’t know if Kang Biso noticed the shift in me, but his tongue stilled, and with a wet, drawn-out sound, he finally pulled away.
His arms slipped from around my waist. The clean, emotionless break left behind a quiet ache, and my head dipped before I realized it.
“Hyung…”
At the soft whisper, I flinched.
Kang Biso lifted my chin with both hands, his palms warm against my cheeks as he raised my face to meet his eyes.
“You’ll stay with me, won’t you?”
The fire in his gaze had vanished. What was left was something raw and vulnerable. His voice trembled, as if he was afraid I’d disappear.
I knew my answer. It was always going to be yes. But the words caught in my throat.
Because suddenly, I remembered my goal.
But before I could respond, his hand began to move—slowly trailing down from my cheek, fingers brushing lightly along the curve of my neck.
It was a simple touch. Innocent even. But it felt dangerously intimate. Not lewd. Not forceful. And yet, every place he touched sparked like live wires beneath my skin.
Like every inch of me he caressed was stripped raw, too sensitive to ignore.
While his fingers traced over my neck again and again, his lips parted.
“You’re going to stay with me… right? Hmm?”
“…I will.”
He sounded like an angel clinging to the last bit of heaven left to him. Something about the way he pleaded made me hesitate—but in the end, I gave him the truth. I did plan to stay by his side, at least while I was here.
At that, a faint smile spread across his lips. That familiar, everyday smile of his.
And just like that, I forgot my mission. Even if only for a moment.
Kang Biso’s hand moved again, this time sliding down my back in a slow stroke.
“Ah…”
A sharp wave of arousal flared, replacing the soft hum that had been lingering inside me. The sound slipped from my mouth before I could catch it.
His eyes narrowed slightly in amusement, and he leaned in—close enough that our lips nearly brushed again.
“…You’re so beautiful, Hwang Seol-bin.”
And with that, he devoured me once more.
His tongue invaded my mouth with practiced ease, wrapping around mine in a deep, heated kiss that left no room for air. My strength drained away so fast I had no choice but to cling to his shoulders.
“Mmh… ngh…”
Every time his tongue flicked against the roof of my mouth, a moan slipped out between our lips.
The longer it went on, the more intense the pleasure became. My body jerked with each breath, my chest tightening. I wasn’t used to a kiss this deep, this intimate. A part of me wanted to pull away—but another part didn’t want this to end.
I wrapped my arms tightly around his neck, holding on like he was the only thing keeping me upright.
“Mm…!”
He sucked my tongue deeper into his mouth, like he wanted to swallow it whole, then finally—slowly—let go.
“Haa… haa…”
A strand of saliva stretched between us before snapping.
My head was spinning. Heat bloomed beneath my skin, and my vision blurred. Through half-lidded eyes, I looked up at him. His lips were red, slick under the light.
And in his eyes, I could see it.
That same raw desire mirrored in mine—only now it was growing wilder by the second.
We stayed like that, breathing in each other’s heat. Then, gently, he kissed me again—softly at first—then began trailing lower.
“Mmh…”
His lips moved from mine to my chin, then along the curve of my jaw, down to my throat.
They paused at the center of my neck, brushing over the most sensitive spot.
“Ah!”
Suddenly—pain. A sharp, biting jolt.
Kang Biso had sunk his teeth into me without hesitation.
The shock made me twist in place, trying to get away, but he didn’t let go.
“Kang Biso—!”
—Slrp.
I called his name in a hoarse whisper. Only then did he release the skin between his teeth, his tongue flicking over the mark to soothe it.
And just like that, a lightning bolt of sensation shot through me—from my throat down to my toes.
What… what the hell is this?
My hands trembled as I pushed against his shoulders, but he didn’t budge.
If anything, he bit down harder.
And then he started sucking.
I knew what he was doing. I’d seen the marks before—on the necks of fellow Special Agents who played around too much. I just never imagined it would feel like this.
If he kept going, I’d end up with the same kind of mark. I tried to block out the rising pleasure, focusing only on pushing him away.
“Please… please stop now…!”
I begged, I pushed, but Kang Biso didn’t stop. Instead, he grabbed the collar of my shirt and yanked it down, exposing my shoulder and collarbone—and then bit down again.
He licked, sucked, marked me over and over. So many times I lost count. The line between pain and pleasure blurred until I couldn’t tell which was which anymore.
“Haa…”
He finally pulled away with a low, satisfied sigh, lifting his head to admire his work.
Then, with his thumb, he brushed over the skin he’d just mauled—slowly, almost lovingly.
It should’ve hurt.
But that one gentle stroke made my body shudder.
“You’re so damn pretty like this.”
He looked down at me with a content, sated grin—like a beast who’d just eaten its fill.
And all I could do was let out a breathless, trembling sigh.
