Setsuna realizes that Haruki has been staying at Kazusa's house this whole time, and she reveals her true self to him: cowardly, introverted, and pathetic.  But Haruki accepts her as she is.  The boundary between them is broken, and the bonds between the three grow stronger as the school fair draws near.  But Kazusa is skipping sleep and food to work on her "last trick" before the school concert.
I'm the one who said all 
those horrible things.
Ich bin doch diejenige,
 die all diese gemeinen Dinge gesagt hat.
Fui yo la que dijo esas cosas malas.
Fui yo la que se puso borde.
Alors que c’est moi
 qui ai été odieuse.
Fui eu que disse aquelas coisas horríveis.
