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 don't think I saw you after the 
swimming club was shut down.
Ich hab dich nicht mehr gesehen, 
seitdem der Schwimmverein geschlossen wurde.
No nos volvimos a ver desde que 
clausuraron el club de natación.
No nos veíamos desde que 
cerraron el club de natación.
On ne s’était pas vus 
depuis la fermeture du club de natation.
Non ci siamo più visti da quando
il club di nuoto è stato chiuso.
Eu acho que nunca mais te vi depois 
que o clube de natação fechou.
Не думал, что увижу тебя после
роспуска клуба по плаванию.
