Onegai!! In Chou!! お願い！委員長！！

Stevenson is a genius and starts his career as a teacher. But he is young, innocent and has no sense of direction. On his first day of the school, he doesn't find even the teacher's room. While he walks around the school, a girl, Chigusa, helps him go to the teacher's room. Chigusa, Haruko and Kanae are good friends and Chigusa starts to like Stevenson. Triggered by Haruko's idea that "He has no confidence as a man.", he has lessons to be a man. Sometimes gently, sometimes severely.... Will he be able to be a real man through H lessons...?
