Souma is worried about his older brother because when he's focused on work, he neglects food and sleep. After discussing it with his friends, Souma decides to make a bento lunch for his brother.
I'm sure your gyūdon
 didn't do him any favors.
الغيودون خاصّتك لم تخدمه كثيراً أيضاً
Dein Gyudon hat dabei
sicher nicht geholfen.
Y tu gyudon lo hará empeorar.
Y tu gyudon no ayuda.
Et ta dose de sel n’a pas dû aider !
Forse il tuo gyudon ha peggiorato la situazione.
E o seu gyudon não deve
ter ajudado em nada.
Своим гюдоном ты ему тоже не помог.
