I agree with people who are saying it's not easy to like Hermione. She is not a likeable person; I think she has a good heart, but honestly, I felt like while Ron was a jerk in GoF, Hermione was just as bad, if not worse, in HBP.

I like to think that HBP made them both mature, especially if they pursue a relationship. Otherwise, it'll be weird. I think R/Hr is canon, but I really think they need to become people I think deserve one another before their relationship is quality.
