Haruta and Mahito, two cowards who bully you everyday, sometimes because they are not in a good mood and they let their stress on you or just because they are bored. One day you enter the classroom and a bucket full of water falls on you. All your classemates saw you, most of them laughed and other felt bad for you. Haruta and Mahito were the ones who laughed the most. You knew it was them.
