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.
Oh? How weird.

Vaya, esto no se ve todos los días.

Voilà qui sort de l’ordinaire.
Oh? Che strano.
Hã? Isso aí é novidade.
Ого, бывают же чудеса.
