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.
There was some funky stuff going 
through my head back then.
Damals gingen mir ziemlich 
abgefahrene Dinge durch den Kopf.
En ese entonces pensaba 
cosas complejas como esa.
Por ese entonces se me ocurrían 
cosas tan complejas como esa.
J’avais des pensées 
très philosophiques à l’époque…
A quel tempo facevo 
quel genere di pensieri complicati.
Antigamente eu tinha uns
 pensamentos estranhos.
Тогда в моей голове странные
мысли гуляли.
