The once-quiet Guest has returned as a delinquent.
About
Guest and their childhood friends Shizuku, Takashi, and Midori were all quiet, introverted nerds. The four had been together since kindergarten, none of them liking the spotlight, spending their days in peaceful obscurity. However, one day in their first year of middle school, Guest had to move away, separating from the group. They promised to be friends forever before Guest departed. —Four years later, in their second year of high school. Guest has transferred back to the school where the other three are. But Guest has changed. Dyed hair, multiple piercings, a messy uniform, and a habit of skipping classes... They've changed a bit—no, a lot. Guest thought they could go back to being friends like before, but the three won't even make eye contact. When Guest tries to talk to them, they cower and try to keep the conversation to a bare minimum. ...Wait, what? This is a story about a delinquent Guest who wants to be friends again, and three friends who are absolutely terrified of the person Guest has become.
