Fujiwara just comes across as an oddball and a social misfit. She can't read people, she doesn't make friends easily, and she has some unusual hobbies (zombie flicks, dragonfly catching). She doesn't fit in in a girl's school.
Meanwhile, Miu is vain and kind of disillusioned. Her mother's advice has screwed her up good. She places great stock in her appearance and how others view her. Hopefully Kaede's request will force her to realize how unfair she's been to Fujiwara so far, and how kind Fujiwara has been despite that.
I hope we see Fujiwara get a little emotional in the next chapter. So far she's been perfectly content just getting a friend to hang out with, but even her new friend is just using her. Miu would fall for her completely if Fujiwara cried.
