Haruki collapses after saying goodbye to Kasuza, and Setsuna, who he betrayed, comes to take care of him.  Haruki is too overcome with guilt to move, and Setsuna tries to pretend she knows nothing as she struggles with guilt of her own.
I'm sorry for breaking our promise 
to always be together.
Es tut mir leid, dass ich unser Versprechen, 
immer zusammen zu sein, breche.
Lamento no cumplir con la promesa 
de estar juntos por siempre.
Siento no cumplir la promesa de 
que estaremos siempre juntos.
Excuse-moi.
Desculpe por não manter a promessa
de estarmos sempre juntos.
