both, but mostly the second. I really like Ron and Hermione, or even Herm and Draco, but Fred and Mione are cute too, though I think that Fred had better matches that he could've made through the books. Get my drift?
It's not the tragedy or anything. I love them together because it's just fun like that. He'd be able to help her loosen up and she'd be able to keep him grounded. I just love the idea of them together.
