After the breakup of his middle school swim team, Ikuya decided to get stronger on his own and not rely on anyone. But then Haruka, breaking out of his freestyle comfort zone to swim in the individual medley, tells Ikuya, "You're not alone." As the two race side by side, Ikuya hears the sound of Haruka swimming, and suddenly he feels something in him changing...
I thought about it, and I realized 
we've never done a relay together.
فكّرتُ في الأمر وأدركتُ أننا لم يسبق
أن سبحنا في سباق تتابُعي معاً
Ich habe nachgedacht und mir fiel auf,
dass wir noch nie eine Staffel geschwommen sind.
Lo pensé y me di cuenta
que nunca hicimos un relevo juntos.
Lo pensé y me di cuenta de
que nunca hicimos un relevo juntos.
Maintenant que j’y pense,
A pensarci su, io...
Eu parei para pensar e percebi que nunca
participamos de um revezamento juntos.
Я подумал и понял, что мы с тобой
никогда вместе не были в эстафете.
