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.
I wanna swim like you!
Ich will so schwimmen wie du!
¡Quisiera poder nadar así!
Ojalá pudiera nadar así.
Je veux savoir nager comme toi !
Vorrei nuotare come te!
Eu queria saber 
nadar como você.
Я хочу плавать так же, как ты!
