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...
there was one kid who was 
always swimming alone.
كان هناك طفل دائماً ما يسبح وحيداً
war immer ein Kind,
das alleine geschwommen ist.
había un niño que siempre nadaba solo.
había un niño que siempre nadaba solo.
et il y avait un garçon
toujours tout seul.
c'era un bambino che nuotava sempre da solo.
tinha um garoto que sempre
ficava nadando sozinho.
был ребёнок, который всегда плавал один.
