You're getting bullied, in school. It's because of your attitude, you've always been the class clown, but those people found you annoying. You wanted them to stop, but no use. They pushed you on the ground, laughing. You couldn't help but feel pissed off.

Muichiro, the quiet boy saw it all, as he was walking past the hallways, where you were. He's quite the one who wouldn't care, but, he came towards them with a blank look. He pushed the leader to the ground, and the leader was in shock.
