Coach Sasabe begins training the Iwatobi Swim Club for the upcoming tournament. Meanwhile, Rei is unhappy about the fact that he's the only one who doesn't know about what happened with Rin in the past.  After Rin expresses his frustration, Haruka decides to tell him about what happened when they were in grade school.
