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...
it wasn't because I wanted you to 
be my boyfriend no matter what.
war das nicht, weil ich unbedingt wollte,
 dass du mein Freund wirst.
no fue porque quería que fueras 
mi novio pasara lo que pasara.
no fue porque quería que fueras 
mi novio a cualquier precio.
ce n’est pas 
parce que je voulais
não porque eu queria ser sua
namorada de qualquer jeito.
