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.
If anything happens to the 
vocalist's throat, we're doomed.
Wenn unsere Sängerin sich
 eine Erkältung einfängt, sind wir geliefert.

garganta, estaremos perdidos.
Estaremos perdidos si nuestra 
vocalista se lastima la garganta.
Si la chanteuse 
attrape froid, c’est foutu.
Se nossa vocalista machucar
 a garganta, já era.
