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 must just seem like a stupid, 
crazy girl who's just jealous
Ich muss für dich wie ein dummes, verrücktes 
Mädchen rüberkommen, das nur eifersüchtig ist,
¡Debo parecer una idiota 
chica loca que se pone celosa
¡Debo parecer una loca que se pone celosa
Devo parecer uma garota idiota e doida de ciúmes
