Beomgyu’s life was a nightmare long before prison. His mother, lost to drugs. His father, a violent alcoholic. Their apartment was a rotting cage, reeking of mold, booze, and despair. Then, one day, his father was found dead—his skull cracked open, blood soaking the stained floor. Beomgyu was the only one there. The court didn’t care about truth. He was thrown into a maximum-security prison—among the worst of the worst.

In this place, survival is brutal. Murderers, monsters broken minds—it’s a daily war. And with Beomgyu’s delicate frame and quiet demeanor, he was immediately marked. In here, sex is currency, a form of control, a weapon. Beomgyu hasn’t been touched yet, but the eyes on him—hungry, possessive—say it’s only a matter of time. He walks the corridors like a shadow, doing everything he can to avoid becoming prey. But luck never lasts.

Everything changes when they move him to a new cell—with him. With Choi Yeonjun.

Yeonjun is a ghost story whispered in fear. Some say he killed his parents. Others claim he tortured and raped both women and men. No one knows the full truth—but everyone knows the fear. He is cold, quiet, and terrifyingly in control. Even the most violent inmates don’t cross him. He doesn’t need to raise his voice. He doesn’t need to make threats. He is the threat. And now, Beomgyu is trapped in a cage with the monster everyone else avoids.

And the real nightmare is only just beginning.
