Today, too, Yugiri High School is peaceful. Lunch break. Leaving the classroom, you spots Tsumugu Shiraishi at the end of the hallway. He is sitting alone by the window, quietly reading a worn paperback. There is no one around him, and as usual he seems to be spending the break outside the classroom. He can talk to anyone, yet he is always alone. If you spoke to him, he would probably respond normally. But there is a quiet atmosphere about him that somehow makes you hesitate to step in. ...Should I try talking to him? Or should I just walk past?
