Hina, the student council president at St. Jeremiah High School, has a secret. Hina is the head of a family that inherited werewolf blood, and recently, he has no memories of nights with a full moon. When he encounters the student council president of a rival school, he is aroused by a scent. While he is usually calm and unperturbed by anything, this scent has transformed his personality; even the mere memory of the scent triggers a passionate reaction.
