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...
Strong enough not to 
break even if I'm alone.
قويّاً بما يكفي لتجنُّب الخسارة ولو كنتُ لوحدي
So stark, dass mich nicht einmal
die Einsamkeit brechen könnte.
Para no romperme si estaba solo.
Para no romperme si estaba solo.
Suffisamment pour nager seul.
Forte abbastanza da
non perdere neanche se sono solo.
Forte o suficiente para não
quebrar mesmo se estiver sozinho.
Сильнее, чтобы не сломаться
даже в одиночестве.
