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.
But that pool is old and not in use.
Aber dieses Schwimmbecken ist alt und wird nicht mehr benutzt.
Pero qué malo que esa piscina 
está vieja y no se pueda usar.
Qué pena que nadie 
utilice esa vieja piscina.
Mais cette piscine est 
ancienne et inutilisée…
Tuttavia, quella piscina 
è vecchia e inutilizzata.
É uma pena que ninguém mais
 usa aquela piscina velha.
Но бассейн-то старый,
он уже не используется.
