The clinking of metal echoed sharply as Kaito yanked hard on the handcuff, pulling Shinichi closer to him. Shinichi felt a burning sting on his wrist as the cold metal bit into his skin. He clenched his teeth, glaring at Kaito.

"Kaito… you’re insane."

Kaito gave a soft chuckle, lowering his head until his black hair brushed against Shinichi’s cheek. "Mm, maybe I am," he whispered, his voice sweet enough to send chills down Shinichi’s spine. "But it’s all because of you, Shinichi. You’ve driven me mad."

Shinichi held his breath when Kaito lifted his chin, forcing him to meet those frenzied violet eyes.

"Do you know how long I’ve been waiting for this moment?" Kaito murmured, his fingers caressing Shinichi’s smooth skin. "The moment you can no longer escape from me."

Shinichi’s hands tightened into fists. "I don’t belong to you. Not now, not ever."

Kaito’s smile faltered, his eyes darkening. "Wrong, Shinichi." His tone dropped into a dangerously low register. "You’ve belonged to me for a long time. You just haven’t realized it yet."

Before Shinichi could react, Kaito gave the cuff a sharp pull, dragging him against his chest. Kaito’s strong arm locked firmly around Shinichi’s waist, leaving no room to evade.

"Kaito! Let me go—"

"Shh," Kaito cut him off, pressing a finger against Shinichi’s lips. "I don’t like it when you raise your voice like that. Unless…" A slow smile curved across his face. "You want me to punish you?"

Shinichi froze.

Kaito’s quiet laugh deepened when he felt Shinichi tremble, his gaze brimming with amusement. "You’re adorable, Shinichi. Even when you’re this scared, you’re so cute I just want to—" He paused, his eyes gliding from Shinichi’s flushed face to the pale column of his neck, and lower to the chest rising and falling rapidly.

"Want what?" Shinichi ground out, trying to keep his voice steady.

Kaito didn’t answer. Instead, he bent down, letting his lips graze Shinichi’s neck. His hot breath made Shinichi flinch.

"Maybe… I should mark you," Kaito whispered, heat lacing his tone. "So you’ll always remember who you belong to."

Shinichi’s eyes widened, but before he could react, a sharp sting bloomed as Kaito’s teeth sank lightly into his skin.

"Ah—!" Shinichi bit down on his lip, refusing to let the pained gasp escape.

Kaito’s lips curled in satisfaction as he gazed at the bite mark. "Adorable," he murmured, his tongue brushing over the reddened skin as if soothing his prey after claiming it.

Shinichi’s fists tightened, every muscle rigid with fury.

"Kaito… I will never accept this."

Kaito tilted his head, as if considering the statement. Then, without warning, he yanked the cuff again, pushing Shinichi down onto the bed beneath him.

"That’s fine," Kaito murmured, his hand stroking Shinichi’s cheek with almost tender care. "You don’t have to accept it. Because I’ll make sure you have no other choice."

Shinichi’s eyes flew wide when Kaito gripped his chin, forcing his mouth open. Before he could resist, a cool liquid spilled into his mouth.

"Mm—!"

He thrashed, trying to shove Kaito away, but a strong hand held the back of his neck in place, trapping him. Kaito’s lips pressed firmly against his, forcing him to swallow the mysterious liquid.

As it slid down his throat, a numbing heat spread through Shinichi’s body. His breath quickened, his trembling fingers clutching Kaito’s shirt, but his strength ebbed away like water slipping through his hands.

Kaito pulled back slowly, violet eyes gleaming with satisfaction at the sight of Shinichi limp in his arms.

"Sleep well, Shinichi," he whispered, brushing his fingers against Shinichi’s flushed cheek. "How does it feel to lose control? Helpless… isn’t it?"

Shinichi tried to speak, but only a weak breath escaped. His body no longer felt like his own—he couldn’t even lift a single finger.

Kaito smiled, carefully unlocking the cuff that bound them together. But just when Shinichi thought he was free, a cold chain snapped around his wrist, fastening him to the headboard.

"I can’t let you run away again," Kaito said softly, stroking Shinichi’s messy hair. "But don’t worry… I’ll take good care of you."

Shinichi bit down hard on his lip, his eyes blazing with hatred, yet all he could do was lie there motionless, staring at Kaito.

Kaito leaned down, pressing a gentle kiss to his forehead.

Shinichi’s eyes grew heavier as the drug coursed deeper into his veins. His awareness blurred, though a thread of fear still lingered.

Kaito stood over him, silently watching as Shinichi sank into unconsciousness—eyes half-lidded, breathing shallow, body limp like a puppet with its strings cut.

A slow smile spread across Kaito’s lips.

"Goodnight, Shinichi," he whispered, his hand stroking the boy’s hair. "You look so beautiful like this."

With deliberate care, he began unbuttoning Shinichi’s shirt, each motion slow as if unwrapping a precious gift. When the fabric slid from his narrow shoulders, Kaito’s fingertips traced the smooth skin, savoring the warmth of the weakened body beneath his touch.

Shinichi didn’t resist. He couldn’t.

Kaito chuckled quietly, removing the rest of his clothes before taking a crisp white shirt from his wardrobe. He dressed Shinichi in it, buttoning each one with painstaking precision, his hands never ceasing their soft caresses.

The oversized shirt draped loosely over Shinichi, enveloping him in Kaito’s scent—an invisible cage.

Kaito stepped back, admiring his handiwork—Shinichi lying on the bed in his shirt, messy black hair against the pillow, pale skin glowing under the dim light.

Perfect.

Leaning down, Kaito brushed his lips against Shinichi’s forehead and murmured:

"From now on, you’ll belong to me… forever."
