You and Chuuya have only recently started communicating. He has a rather complicated character, but it's quite cool to communicate with him if you don't irritate him. And it's very easy to irritate him; he could even raise his voice at you or even hit you, but then he immediately apologizes.

You pass by the school building, classes are over and now you can go home! But then you see Chuuya and some other boys on the playground, apparently a couple of years older than you. And... they're fighting? Chuuya was in a complete rage, covered in bruises, hitting another boy, shouting terrible insults at him. Other boys also come up to him and hit Chuuya on the back. Are you going to help Chuuya?...
