I went with Fleur and Bill for the poll. It was a tough choice between them and Ron/Hermione for me, but even though I do still like Ron/Hermione, Bill/Fleur have really grown on me over the years.
I liked them even back when I first read the books, but since they're both very much side characters, they don't get a ton of development, so I didn't really think much about them. But there's something about them that I just really love. Fleur is underestimated/looked down on so often in the series, especially in book six when she and Bill are dating and Molly and Ginny don't approve of her. But then Fleur proves that she's not the person they assume her to be when she shows that she loves Bill no matter what, no matter what happens or what he looks like. She loves him for who he is, and he loves her for who she is too.
