Zenya Kaiho enrolls in a rough and dirty all-boys' school. At a glance, he looks like a troublemaker, but actually, he's just an ordinary guy. In the midst of this filthy school is Chizuru Hanazono, a good-looking, intelligent Prince Charming. However, after Chizuru makes a nasty remark over a trivial matter, Zenya becomes upset and wants to pay him back. He discovers a hypnosis app that can control people at will and uses it on Chizuru as a joke, but the app turns out to be very effective…?!
