Aoki tells Yushi that he must be suffering without his parents, even though he isn't.  She has good intentions, but Yushi is frustrated by her inability to see who he really is, and insistance that he has to be what she thinks he is.
I can leave you alone, without worry.
يمكنني تركك وشأنك بلا قلق
Ich kann dich ohne Sorge
alleine lassen.
No tengo de qué preocuparme.
No tengo de qué preocuparme.
J’ai pas à faire la police.
Ti lascio in pace, 
so che posso stare tranquillo.
Posso ficar tranquilo.
Не волнуйся, я не буду приставать.
