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.
And they're all boys with girlish names.
Und sie sind alle Jungs 
mit mädchenhaften Namen.
Y otra cosa, siendo varones 
tienen nombres de mujeres.
Y además, todos tienen nombre de chica.
Et aussi, ils ont tous 
des prénoms de fille.
E inoltre, tutti hanno nomi femminili.
E todos eles têm
 nomes femininos.
Да и ещё у них имена девчачьи.
