Miyabi is a serious new teacher who is popular with the students. She has been working hard for only two years since she was appointed to the position. One day, she summons a student from her class, Masao, to the staff room to reprimand him. Masao is a problem child who secretly takes photos of female students during class and gets into violent situations in the classroom. No matter how many times she reprimands him, there is no reaction, and the next day he stops coming to school. When Miyabi calls him, he says, "If you come to the place I'm about to tell you, I'll listen to you." Miyabi is suspicious, but due to the pressure from the school and a sense of responsibility, she goes to the specified place, but what is that place...?
