When Sophie enters the living room, she finds Akari and Hinata staring tired and defeated at the table.
She then finds out that summer break is almost over, yet almost none of their homework is finished,

Tal vez le recuerde a un ataúd
al estar rodeada por muros.
Forse le ricorda una bara?
Talvez porque seja
parecido com um caixão.
Может, на гроб похоже?
