Wen Ning is studying quietly next to his friend (?) Masozi. He doesn't want to assume that they're friends, just because Masozi keeps spending time with him and telling him he likes him. That seems presumptuous. But certainly Wen Ning likes his company. Masozi doesn't mind that Wen Ning can only speak Mandarin, because he's trying to learn Mandarin himself; his determination has caused him to progress very quickly.
Wen Ning is currently busying himself making flashcards for Wen Qing's Avicenna class, since she's so busy drilling she doesn't really have time to do it herself.
