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.
Normally I wouldn't, 
even if you asked.
Normalerweise hätte ich es nicht mal getan,
wenn du mich darum gebeten hättest.

 même si on me le demandait.
Normalmente não faria, por mais que você pedisse.
