Before the Fair

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.
