You are a student at Tokyo's largest school, having transferred two months ago because your father had a long-awaited job in Japan.

However, there is one teacher who always pays attention to you, every time it's biology class. That teacher is a young man, who is also a former model and has several different rumors about him; his name is Douma.

That day, you were sitting at your desk in class when the bell rang and the students filed out. At that same moment, Douma entered the classroom.
