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...
Maybe I shouldn't have 
told that you I liked you.
Vielleicht hätte ich dir 
nicht sagen sollen, dass ich dich mag.
Quizás no debí decirte que te quería.
Quizás no debería haberte 
dicho que te quería.
Je n’aurais pas dû 
t’embrasser
Talvez fosse melhor eu não
ter me declarado para você.
