Jun decides to help Shiena with her studies, which drives Naori crazy. Rumi, on the other hand, seems unusually indifferent about it. However, for Naori, it's clear that she needs to keep an eye on them. So, she quickly invites herself along.
Keep oversleeping, and you'll
 have to repeat the year.
،إن استمريت بالاستغراق في النوم
.فستعيدين السنة
Wenn du weiter ständig verschläfst,
bleibst du sitzen.
Sigue durmiéndote
y acabarás repitiendo.
Sigue durmiéndote
y acabarás repitiendo curso.
Tu vas finir par redoubler,
tu sais.
Continua a fare la dormigliona
e verrai bocciata.
Se ficar dormindo desse jeito,
vai repetir de ano.
Иначе тебя на второй год оставят.
