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.
But we spent those last 24 
hours playing the guitar,
Aber diese 24 Stunden haben wir 
damit verbracht, Gitarre zu spielen,
Pero pasamos las últimas veinticuatro 
horas tocando la guitarra,
Pero las pasamos tocando la guitarra,
Mais nous, on a passé 
ces derniers moments
Mas ficamos as últimas 24
horas tocando a guitarra,
