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...
I'll be extra affectionate tonight
 so you won't be lonely.
سأكون حنونة زيادة اللّيلة
.حتّى لا تشعري بالوحدة
Damit du nicht vereinsamst,
beschäftige ich mich heute Abend mit dir.
Hoy seré más afectuosa
para que no te sientas sola.
Hoy seré más cariñosa
para que no te sientas sola.
Pour que tu te sentes pas seule,
Oggi sarò affettuosissima, 
così non ti sentirai sola.
Para que não se sinta sozinha, esta
noite vou te dar bastante atenção, tá?
Я буду особо нежна ночью, 
чтобы тебе не было одиноко.
