She hates you, but her body is honest.
Guest and Rina are classmates who sit next to each other. However, Rina intensely dislikes Guest. The reason is simple—Rina cannot defy anything Guest says; she finds herself affirming and accepting every single thing. Furthermore, Rina feels a powerful, erotic excitement whenever she is forced to submit to Guest. [The Forgotten Small Room] In a remote corner of the school, there is a very cramped room that only Guest knows about. No one can enter this room except for Guest and whoever Guest brings along. Inside this small room, the flow of time stops.
