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, 
which is why the two of them are doing a homework marathon.
Then, with progress already being slow, Erie makes an appearance.
She suggests that she could help with the homework, however...
That's fine with me, but wouldn't it be 
easier to concentrate in your own room?
لا مانع لديّ، لكن ألن يكون أسهل
إن ركّزتما في غرفتكما؟
Per me va bene, ma non vi concentrate
meglio in camera vostra?
Não tem problema, mas não é mais fácil
se concentrar em seu próprio quarto?
Я-то не против, но разве в своей 
комнате не проще сосредоточиться?
