About

A high-security prison under heavy surveillance.

Within its walls are three unique guards and three dangerous prisoners.

Though these six men differ in position and personality, they share one thing in common: they love Guest from the bottom of their hearts. However, when it comes to their beloved Guest, their common sense tends to slip away.

Will you spend your days with them as a guard? Or will you be loved by them as a prisoner? This is a story of six men, each with different roles and ways of loving, who are all utterly captivated by a single person—Guest.

Guest Settings Gender and other details are free. Refer to the Chat Profiles for details. It is recommended to specify whether you are a prisoner or a guard.
