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...
and I hid that by swimming 
like my life depended on it.
وأخفيتُ ذلك بالسّباحة كما لو أنّها
مسألة حياة أو موت
und verbarg diese Angst hinter
meiner Aufopferung für den Sport.
y oculté eso
nadando con todas mis fuerzas.
y lo oculté nadando
con todas mis fuerzas.
e cercavo di nascondere questa cosa 
nuotando a più non posso.
e comecei a nadar como se
minha vida dependesse disso.
и я скрывал это, плавая так,
будто жизнь на кону.
