I love their love and hate relationship, and the bickering and so on. That is what really told me early on that these two would end up with each other. Their relationship is realistic to me. I love how JKR did it, she didn't make them just fall head over heels with each other, that's lame and predictable. Also, Emma and Rupert have great chemistry, ones may disagree, which I think is completely ridiculous. They have more than Bonnie and Daniel. They play well off of each other and you can see it. They remind me of an old married couple, which is completely endearing. Romione forever!
They are just adorable together. She brings out the best in Ron and he brings out the best in her. They truly have real feelings for each other. They like each other for who they really are.
Their relationship is realistic is common :) I mean, it mind start out as playful bickering, but come on, as we age, we all know that those bickering add up to sexual tension ;)
