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.
Is it okay for just the 
three of us to dig it up?
Ist es ok, wenn nur 
wir drei es ausgraben?
Me refiero a que si está bien que 
nosotros tres nos pongamos a excavar.
Me refiero a si está bien eso 
de recordar viejos tiempos.
Sarà giusto anche se siamo 
solo in tre a dissotterarlo?
Vamos desenterrar aquilo só nós três?
Ничего, что мы втроём выкопаем его?
