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...
If I got to you before Kazusa, 
I knew I could beat her.
Ich wusste, dass ich sie schlagen könnte,
wenn ich ihr zuvorkommen würde.
Que podría vencerla si llegaba 
a eso antes que Kazusa.
Que podría vencerla si llegaba 
allí antes que Kazusa.
Je savais qu’en m’y prenant 
avant que Kazusa t’avoue ses sentiments,
Eu sabia que se fosse antes
da Kazusa, poderia vencê-la.
