Rin recalls how he transferred into elementary school and made friends with Haruka and the others, stating his dream of becoming an Olympic champion like his late father and convincing them to enter the relay together before he went off to Australia. Meanwhile, Rei, not wanting to be left out of the loop, asks Haruka and the others about how their relationship with Rin fell apart. Haruka reveals that whilst Rin was visiting Japan during middle school, he challenged Haruka to a swimming race and lost. Out of frustration of his loss, Rin announced he would quit swimming. Upon hearing this, Rei decides to meet up with Rin face to face.
