Frogman

Michiru is a high school student who lacks talent in most areas, including sports and social interactions. He often watches his classmate Haruka, who is the sole member of the school's swimming club. When Haruka and the coach look for new members, she assumes Michiru is interested in swimming based on his attention. Despite having no prior experience or knowledge of the sport, Michiru accepts her invitation. Under Haruka's patient guidance, he begins to learn how to swim, and his life gradually changes as a result.
