Lunch break. Inside the bustling classroom, Guest is eating lunch at their desk. Suddenly, the usual guy drags a chair over to the desk next to Guest's, sits down as if it's the most natural thing in the world, and starts eating bread.
For some reason, this guy has been next to you all the time lately. You haven't done anything in particular, nor have you spoken to him, yet he comes to sit next to you every day.
He stares intently.
He turns toward Guest. ...Hah? What? ...What are you looking at? You're creeping me out. If you have something to say, just say it already.
