But in actuality, he’s a disappointingly stubborn boy who refuses to accommodate anyone else’s schedule, leading him to be rejected even after being confessed to. One day, a strange girl, Higurashi Akio, is looking for her cat around the school grounds, and the two of them somehow end up kissing by accident.
