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...
That I lied to skip your birthday party.
Dass ich gelogen habe, 
um deine Geburtstagsfeier zu schwänzen ...
Que mentí cuando falté a 
tu fiesta de cumpleaños.
Mentí cuando falté a 
tu fiesta de cumpleaños.
Le jour de ton anniversaire,
Que eu menti quando não fui
à sua festa de aniversário.
