So I can understand why people would like Harry/Hermione because they are best friends and they do love each other, but there are some odd couplings that I don't understand and I would really like some explanation why it is people who like them.

Pairings like Draco/Hermione and Ginny/Draco I just really don't get when in the books they really hate each other.

So I'm just wondering if someone could explain it to me. I don't want to start a fight I'm just really interested and curious about this.

A little help please?
