Okada Mengnan (Lianghei Suzuki), as his name, is a burly high school student with a height of two meters and a weight of two hundred jin. In school, the fierce boy is deeply trusted by the back of the community and is an unshakable idol in the eyes of future generations, but in the eyes of girls, the ferocious and ferocious man has no intention of being a nightmare, and whoever is caught by him will feel cold behind him. There is always a very disharmonious figure around the fierce man, that is, Shinagawa, a childhood sweetheart (Kentaro Sakaguchi), who has been playing together since kindergarten. Shinagawa is a standard beautiful man, one rough and one handsome. The two became a strange landscape on campus. And Shinagawa repeatedly rejected the girls' confessions for nothing else, just because they all said bad things about fierce men behind their backs. One day, the fierce man met a girl named Daiwa (Nagano Yayu). He thought that he had also fallen in love with the fierce man of Shagawa Cheng, only to find that his real goal seemed to be him.
