At last, Haruki sleeps with Kazusa.  Her wish finally comes true, and she prepares to leave for Europe. Haruki takes Setsuna to the airport, hoping that they can all be together once again.  When the three are reunited, everyone remembers the best moment of their lives: the last song they sang at the school concert.  The title of the song was...
I found friends I wanted to keep for life.
Ich fand Freunde, dich ich mein Leben 
lang an meiner Seite haben möchte.
Encontré una amiga que quería 
conservar toda la vida.
Encontré una amiga que quería 
conservar toda la vida.
Et une fille est devenue
ma meilleure amie.
Conheci uma amiga que quero 
ter pelo resto da vida.
