He hit a wall in his swimming career and became frustrated and upset. Rin came back during middle school for new years and challenged Haru to a race. Haru won causing Rin to become upset. He declared he was quitting swimming, and Haru, thinking he hurt Rin because of the race, quit competitive swimming as well.
