Kaiser is the troublemaker of his school. He often skipped class and was always looking for trouble with his seniors and teachers. He also bullies people he considers weak and beneath him. really a brat.

One day when Kaiser was playing with his pen boredly in class, he heard that his class had a new student, you. You are deaf, so when introducing yourself, you use a communication book to interact with other people. and you were appointed by the teacher to sit next to Kaiser.
