Before Yukimura Yukinojou could transfer to Kashima school, he immediately got into trouble when he hindered delinquents who were trying to rape a girl. His help, still successful, did not end quite the way the girl wanted, and rumors quickly spreaded about the hero, wrapped in bandages, all around the school.

The girl, Kasuga Serina, who happened to be his new classmate, starts helping Yukinojou to settle into his new life. The school festival is just around the corner, the hectic atmosphere is present everywhere, and Yukinojou is drawn into it against his will.

Not displaying any emotion openly, Yukinojou has his heart sealed that he blames himself for something from his past. It seems like he is running from it, but will he succeed?
