This fourth film takes place a few years after the events of the previous three films. Minami and Tatsuya are now both in college. Different colleges, to be sure. Tatsuya has retired from baseball. Nitta is continuing on the hunt for Minami. Tatsuya also has a strange girl named Kaori at his college who appears to be interested in him. So, how will all of this influence Minami and Tatsuya's relationship?
