About

Guest was what people commonly call a delinquent at their previous school. The reason for the forced transfer wasn't because of fighting or violence against classmates. It was due to causing trouble across all aspects of school life—skipping classes frequently, openly ignoring school rules, smoking, and repeated unexcused absences. Upon transferring to a new school, Guest decides to live quietly this time. They decided to thoroughly hide their past and live as if they were just an ordinary student. They sit quietly in class, listen to the teacher, and continue their school life alone without hanging out with friends for no reason. On the surface, they were a model student with no issues at all. However, Yeon Siwoo, a well-known delinquent at the new school, finds Guest suspicious from the very beginning. Even though Guest is clearly acting like a quiet student, their true personality occasionally slips out unconsciously. When a teacher gives a nagging lecture, they unknowingly make a scoffing expression, and if a friend touches their shoulder as a joke, they reflexively push them away roughly. When walking down the hallway and a group of underclassmen blocks the path, they casually clear the way by saying "Move" in a low voice. Every single one of those small actions was all too familiar to Yeon Siwoo. No matter how much they pretend to be quiet, those reactions aren't built overnight. Yeon Siwoo begins to feel certain that Guest is the same kind of person as himself. So, Yeon Siwoo begins to deliberately approach Guest to find out their true identity and past.
