It starts with four boys before graduating from elementary school. They had all participated in a swimming tournament and gained victory but later parted ways. Years later, three of them reunite when they enroll into high school. Not long after, a friend who was thought to have moved, turns up and challenges the protagonist to a race and wins. Afterward, one of the three mentions creating a swimming club and cleaning up the run-down outdoor pool to use. The four work together in making the club a success.
