Iku and Keita have been buddies since childhood, and have played sports together their whole lives... until their final year in middle school, when Keita's baseball career abruptly ended as a result of the severe injuries he sustained when saving Iku from being hit by a truck. Ever since that accident, Iku has distanced himself from both the game and his friend, presumably out of guilt. Can these two friends patch up their differences, and become something more...?
