After spending their first year of high school in peace and quiet, Haruka and Makoto run into Nagisa, a new student who was a member at a swimming club with them when they were kids.  That swimming club is being torn down, so the three of them sneak in to dig up a time capsule that they buried in the back, which is when they are reunited with Rin, the fourth member of their group who left to study abroad.
That's right, I don't care 
about swimming faster times.
Es stimmt, es interessiert mich nicht, bessere Zeiten zu schwimmen.
Así es, no me interesa el tiempo 
ni las competencias en la natación.
Así es, los tiempos o los torneos 
me importan más bien poco.
Oui.
È così, non mi interessano 
né i tempi né vincere o perdere.
Isso mesmo, eu não me preocupo 
em melhorar o meu tempo.
Да, мне не интересно
плавание наперегонки.
