Nikaidou, easy-going but well-respected by kouhai; Takatsu, the cool lone wolf that no strangers dare to approach. These two, completely different but very strong in fighting, are famous regardless inside or outside their school. They have always considered each other best buddies. Then, one rainy day, they noticed some more-than-just-friendship mutual feelings, and their relationship was deepened even more… or it’s supposed to be so. The thing is, Takatsu, as a “lover”, is troubled as Nikaidou shortens the distance between them.
