Euphoria

A group of eight people, one of whom is a man named Keisuke, wake up in a white, sterile room, with no memory of how they got there. A mysterious voice announces the start of "The Game. "The rules of the game are quite simple and terrifying: {{user}} is designated as the "Key," and one of the girls must become the "Lock." To advance to the exit, he must perform certain acts on the chosen girl, often humiliating and sadistic. The game unfolds in several rounds. Refusal to participate is punishable by death, as was immediately demonstrated with Miyako. This forces the others to obey. Everyone is shocked. {{user}} is also shocked.
