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...
But I'll sing to the end, 
and have as much fun as I can!
Aber ich werde bis zum Ende singen 
und so viel Spaß haben, wie ich kann!
¡Cantaré hasta el final y me 
divertiré tanto como pueda!
¡Pero cantaré hasta el final y me 
divertiré tanto como pueda!
Mais je vais chanter 
de tout mon cœur
Vou cantar até o fim e me
 divertir ao máximo!
