A class observation day was scheduled to be held in Gaku's class. However, Gaku was worried that if Hayato took a day off to attend, it would cause inconvenience at his workplace and increase his workload.
I got an energy boost after dinner and figured it out!
Es hat wohl geholfen, beim Abendessen
Kohlehydrate aufzutanken.
Parece que me sirvió
recargar energías con la cena.
Le dîner m’a apporté les glucides
dont j’avais besoin.
Dopo aver cenato, mi sono sentito 
pieno di energie e ho capito come fare!
Fiquei cheio de energia
após o jantar e resolvi tudo!
После еды мозги заработали лучше!
