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.
It's all your fault for teaching me 
how much it hurts to fall in love.
Es ist deine Schuld, dass ich erfahren habe,
 wie sehr es schmerzt, sich zu verlieben.
Es tu culpa por mostrarme 
cuánto duele enamorarse.
Es culpa tuya enseñarme 
lo que duele enamorarse.
Il ne fallait pas m’enseigner 
la douleur d’aimer un garçon.
É culpa sua por me mostrar como dói se apaixonar.
