S1E10 Irritated Heart Rate!/Plot

The episode started with Rin's introduction as the new transfer student of Iwatobi Middle School. Rin tells the class that even though he has a girly name, he is in fact a boy.

As the episode continues, flashbacks on how Rin joined the swimming club and how he formed the relay team together with Nagisa, Makoto and Haruka are shown.

Goro decided to continue coaching them for their relay competition. He continuously urges them to practice more and take note of their faults like swimming form, kicks and time.

After the team finished on one of their practices, Nagisa, Makoto, Rei and Haruka together with Gou, Goro and Miho had a hot pot in Goro's house even though it's summer.

There, Gou discovered the old clubs photos, which of course includes Rin in it.

On the way home, Rei asks the other three on what happened to their relationship with Rin, knowing that the old photos showed how close they were before.

Haru tells Rei about Rin's obsession on swimming relay and that event where Rin and Haru raced which ended Rin's loss when he came back from Australia.

The next day, Rei skipped practice and went to Samezuka Academy to talk with Rin.
