Nasa, at the request of his former junior high school teacher, Ms. Yanagi, finds himself entrusted with teaching a programming class at a high school. But here's the catch—it's an all-girls' school. Surrounded by the limitless energy of teenage girls, Nasa tries to maintain his composure, but deep down, he can't help feeling nervous.
