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.
Does that mean you wouldn't have an issue 
with me going with you when you tutor her?
أهذا يعني أنّك لن تمانع
قدومي معك حين تذهب لتدريسها؟
Dann hättest du also nichts dagegen,
wenn ich dabei wäre, wenn du mit ihr lernst?
Pues no te importará
que te acompañe a darle clases, ¿o sí?
Entonces no te importará
que vaya contigo a darle clases, ¿no?
Du coup, je peux t’accompagner
quand tu l’aideras ?
Quindi non c'è problema se ti accompagno
quando le dai ripetizioni, giusto?
Nesse caso, quando você for dar
aulas pra ela, tudo bem eu ir junto?
Значит, ты не против, если я
понаблюдаю за вашими занятиями?
