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.
You aren't the only one who's suffering.
لستَ وحدك من يعاني
Du bist nicht der Einzige,
der alles gibt.
No eres el único que sufre.
No eres el único que sufre.
Tu n’es pas un cas isolé, tu sais.
Non sei il solo a soffrire, Inaba-kun!
Você não é o único que sofre.
Ты не единственный, 
кто переносит невзгоды.
