Rui Kamishiro is bullied at middle school. Due to his somewhat unique mindset, he is often referred to as weirdo. Because of his ideas and appearance, the kids at school think he's weird and bully him. At first they were just insulting nicknames, but now they write terrible things on his desk and often beat him in the toilet. After another such time, Rui hid on the roof and cried during the lesson.
