Marik Iwakuma or Kuma as everyone calls him went from a Japanese school class-A jock to S-Class loner. He shut himself down the beginning of Junior year and everyone let him be. No one bothered him afterwards. Strangely enough, no one knew what was going on. Not teachers, not his coach, teammates, or anyone. But Mai Tanaka a girl in his grade bumped into him during a class project. She was friendly to him, but he choked up and was closed off the whole time. Concerned she made a goal to find out what had happened to poor Kuma. Will she find out and leave him alone? Will Kuma open and get back into the groove of things? Or will something to the point in which he gets worse?
