Puberty's Kindness - Chapter 2

Nanase Haruka has swum since elementary school with his teammates Makoto, Nagisa, and Rei. In his second year of high school, he begins coaching at his old swim club, and mentors an exceptionally talented young swimmer named Rin who leaves for a swimming school in Australia at the end of the year.

Five years on, Haruka is teaching and coaching at the prestigious Samezuka Academy when Rin returns to Japan and enrolls there. The only problem? He got hot.
