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,

It's hard for me to sleep like this...
...من الصّعب عليّ أن أنام هكذا

Así no puedo dormir.
Así no puedo dormir.
Je peux pas dormir comme ça.
Mi viene difficile dormire così.
Está difícil de dormir assim...
Я так не усну...
