I thought that , the whole time I read the books

I am not picking this because of both loving to read, but both are really brave and loyal. They are also both really bright.

I've felt for a while now that Belle is a bit like a princess version of Hermione. They both see who people truly are underneath the surface, and both have a stubborn streak in them, as well as the more obvious things.
As a couple, I think Bill and Fleur have a few similarities to Beauty and the Beast (part werewolf and Veela, for example).

I know she's an obvious choice, but still. Maybe Remus, both outcasts.

I actually see the Remus comparisons, both being outcasts in their own communities.

Smart and brave
