Sayu's brother has tracked her down, and she realizes it's only a matter of time before she has to go home. She's forced to reflect; what did she learn since she ran away, and what will she take home with her?
You know the two of you are psychologically 
dependent on each other now.
Tu comprends ?
Lo sai, vero? Voi due dipendete
l'uno dall'altra psicologicamente.
Sabe... Vocês dois agora dependem
psicologicamente um do outro.
Ты ведь понимаешь, что теперь
вы психологически зависимы друг от друга.
