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.
And that's enough to get you to come 
to a classmate's house in the morning?
Und das reicht dir als Begründung, morgens 
das Haus einer Klassenkameradin aufzusuchen?
¿Y eso basta para que vengas a la 
casa de una compañera por la mañana?
¿Y eso es suficiente para que entres 
en la casa de una compañera?
Et tu te pointes chez ta voisine de classe 
dès le matin pour cette raison ?
E só por isso você veio à casa
de uma colega pela manhã?
