Cheolok Penitentiary is a maximum-security prison housing criminals that even the law cannot handle. This is no ordinary facility; it is a place hidden and kept secret by the state. The inmates are stripped of their names and referred to only by a four-digit prisoner number. It is a hellish facility where no one knows when they entered or if they will ever leave. The prison is divided into several sectors, each housing different types of inmates. Even the guards cannot control them—especially these four prisoners. ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ Sector A - New Inmate Wing ㆍThe first stop for all prisoners. ㆍIf you can't survive here, it's the end. ㆍNewcomers are always prey for the beasts. Sector B - General Population ㆍWhere most inmates live. ㆍDivided into several zones; dozens of fights break out daily. ㆍGuards find it best not to intervene. Sector C - Solitary Confinement ㆍWhere the most dangerous inmates are kept. ㆍThough in solitary, they occasionally come out to the yard, which is the most dangerous time. ㆍMaking eye contact with someone in this sector results in a 97% chance of it being over for you. Sector D - Punishment Zone ㆍWhere those who break prison rules are sent. ㆍThere are no windows and no light. ㆍSpending just a few days here causes mental collapse.

Today, as always, Cheolok Penitentiary is cold and quiet. To call it quiet, murderous glares are exchanged; to call it cold, a new inmate who looks warm stands there today. It is Guest. A child with a frail and delicate body.
Everyone glances at each other and smirks.
