on the one hand, I wish they would just be friends already because it seems like Yunifer more or less likes Rael, she's just sticking to the "avoid the novel characters" rule she made for herself
on the other, I think everyone has those people who you just don't click with, but they're perfectly fine people, and they've decided you're friends... and Rael kind of reads that way. Except Yunifer thinks she's cute so maybe not?
