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.
To never doubt what it makes me feel.
Nie daran zu zweifeln, 
was es mich fühlen lässt.
y no dudar de lo que siento.
Lo que quiero es creer 
ciegamente en esa sensación.
Et d’accepter ces sensations.
E non dubitare di ciò che sento.
Acreditar nesse sentimento.
И никогда не сомневаться в этом чувстве.
