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.
Don't take your clothes off here!
Zieh dich doch nicht hier aus!
¡No te la quites aquí!
¡Pero no te quites la ropa aquí!
Ne te déshabille pas ici !
Non puoi svestirti qui!
Não tire suas roupas aqui!
Не смей раздеваться тут!
