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 knew how you felt, 
and how Kazusa felt.
Ich wusste, wie du fühlst, 
und ich wusste, wie Kazusa fühlt.
Sabía cómo te sentías 
y cómo se sentía Kazusa.
Sabía cómo te sentías 
y cómo se sentía Kazusa.
Je savais ce que vous ressentiez 
l’un pour l’autre.
Eu sabia como você se sentia
 e como ela se sentia.
