Unable to stand being treated by a child by Haru, Ren leaves the house. Natsuo agrees to let Ren stay over when he suddenly shows up at his apartment, but Haru shows up just as he's about to grant Ren's request to do something that he "can't tell Haru about." Haru tells  Ren to not come home ever again, but...?
He must be tired of playing 
the difficult younger brother.
Er muss es leid sein, immer den
schwierigen, jungen Bruder zu spielen.
Debe estar cansado de hacer
de complicado hermano menor.
Debe de estar cansado de hacer
de complicado hermano pequeño.
Y en a marre d’être traité 
comme un petit frère irresponsable.
Dev'essersi stancato di fare la parte
del fratellino difficile.
Ele deve estar cansado de brincar 
 de ser o irmão complicado mais novo.
