To her surprise, as a new boarder she has to pass a courage test that involves sneaking into the boy’s dorm. While escaping from the teachers, she ends up running into the bedroom of the school’s “bad boy”, Wanibuchi, but instead of harassing her, he helps her escape! Though Wanibuchi’s incredible height and rumors of his violent past scare everyone away, Eimi can’t help but find herself being drawn to his mysterious charm and beautiful physique. Will she listen to her classmates and stay away, or will she follow her heart and be the one to tame the beast?
