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 just have this habit of just 
compressing things down to their vital points.
Ich habe nur die Angewohnheit, 
Dinge aufs Wesentliche zu reduzieren.
Tengo el hábito de comprimir 
las cosas a lo más importante.
Tengo el hábito de quedarme con lo importante.
j’ai l’habitude de récapituler
 au fur et à mesure…
Eu tenho essa tendência a resumir
tudo aos pontos essenciais.
