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...

Pero sabía que me aceptarías igualmente.
Mais à ce moment-là,
Mas eu sabia que você me aceitaria
 assim mesmo na época.
