Yumeji has a big problem – and no, it's not that he's gay (for now, anyway). Despite his good looks, excellent grades, and talent for sports, he's not getting any! It has everything to do with the fact that he's impotent thanks to a traumatizing event back in middle school. Nothing seems to help, and since Viagra is apparently not a viable solution in Japan, he's practically lost all hope – until he meets underclassmen Seiji, who's violent, tactless, and says whatever is on his mind. Conveniently enough, he's also in love with Yumeji.
