Hikari tries to be a good big brother to Hinata, but works a little too hard. Hiromu's parents try to make up for the years they've lost with their son and his family.
I suspect it's an "effort fever," though.
Ist aber sicher nur Wachstumsfieber.
Aunque creo que es
por esforzarse demasiado.
Creo que le ha subido
de tanto esforzarse.
Mais bon,
je pense qu’il ira vite mieux.
anche se credo sia solo dovuta allo sforzo.
Mas suspeito que seja
uma "febre do esforço".
Но думаю, это от стресса.
