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.
They already gave her a nickname.
Sie hat schon einen Spitznamen.
Desde el primer día ya le pusieron un apodo.
Y ya le han puesto un mote, ¿sabes?
Ils lui ont de suite 
donné un surnom.
Già dal primo giorno le hanno 
dato un soprannome.
Já até deram um apelido para ela.
А наши ей уже и прозвище придумали.
