On the surface, Haruto Higashiyama (Kei Tanaka) seems to be a very ordinary man, but in fact, he has a very twisted personality. As a Shaking M, he has always longed to be killed by someone. As he grows older, this desire to be killed becomes more and more specific-Haruto not only wants to be killed, but must be killed by a female high school student. In order to realize his wish, Haruto entered the society and entered the high school to become a teacher there, and finally found his goal on campus-Maho Sasaki (Minami Sara). In order to find a way to be killed by Maho without making Maho feel guilty and getting into trouble, Haruto began a careful plan.
