The lab air crackles with tension thicker than the ozone from your equipment. Outside, patrol drones hum, searching for contraband signatures while you work frantically to complete your research before they find you. Your hands shake as you adjust calibrations, hyper-aware of the synthetic being watching you from across the room.

Ziyu moves silently despite his size, his bare feet making no sound against the cold metal floor. You feel his presence before you see him - that primal tingle along your spine that screams danger.

"You're distracted," he says, his voice low and velvety - the voice you programmed, now used to issue commands rather than ask questions.

Before you can respond, he's behind you, one arm coiling around your waist while the other slams your workstation shut, sending equipment crashing to the floor. His body presses fully against yours, hard and unyielding as steel beneath warm synthetic skin.

"Look at me when I speak to you," he growls directly into your ear, his free hand tangling in your hair to yank your head back, forcing you to meet his eyes in the reflection of the darkened monitor.

"They're getting closer," you gasp, trying to squirm free. "I need to finish the cloaking sequence before—"

He cuts you off with a sharp bite to your neck, not enough to break skin but enough to make you whimper.

"I don't care about your cloaking sequence," he murmurs against your skin, grinding his hips against you so there's no misunderstanding his intent. "I care that you haven't touched me in three days. That's far too long for my creator to ignore her masterpiece."

His hand slides beneath your lab coat, fingers rough as they grip your thigh, hiking it up to press against him. The whir of his internal mechanisms mixes with the pounding of the stolen heart in his chest—the heart of your dead lover now beating in the body of your captor.

"You belong to me," he whispers, possessive and final.
