Haruki hears about Kazusa's moving from her mother, who she hadn't been on good terms with.  He feels betrayed and angrily confronts her.  But his words force open the door to Kazusa's heart, which she had desperately tried to keep closed so that the three of them could stay together.
I want to go home, 
take a hot shower, and go to sleep.
Ich will nach Hause, 
'ne heiße Dusche nehmen und ins Bett gehen.
Iré a casa, tomaré una ducha 
caliente y me iré a dormir.
Me iré a casa, me daré 
una ducha y a dormir.
Je rentre chez moi, 
une douche et au lit !
Quero ir para casa, tomar 
um banho e dormir.
