Kazusa's overworking finally catches up to her, and she collapses two days before the school fair.  Haruki cares for her as he continues to practice his guitar.  Kazusa, in a (possibly) fevered state, tells him about her troubled relationship with her mother Youko.  But meanwhile, at the concert rehearsal in the gym, Setsuna is separated from the other two and feels lonely and afraid her first time on stage.
Kitahara wrote the lyrics, 
I added the music, and you'll sing it.
Kitahara hat die Lyrics geschrieben, 
ich die Musik komponiert und du wirst es singen.
Kitahara escribió la letra, yo añadí 
la música y tú la cantarás.
Kitahara escribió la letra, yo añadí 
la música y tú la cantarás.
Kitahara a écrit les paroles,
Kitahara escreveu a letra, eu fiz
a melodia e você vai cantar.
