Because
"Really, Hermione, we thought you'd've gone for someone else. Viktor Krum, maybe, he was always mad about you. Why Ron?"
It was Parvati who asked, but half a dozen other girls' faces mirrored her curiosity. Hermione had known that having a hen night was asking for trouble, but Ginny had begged her to follow the Muggle custom, and she had given in.
"I mean, we know he saved your life and all, but still..."
Hermione wondered if the slight face Lavender pulled wasn't jealousy, although one would think after six years and at least eight other boyfriends, Lavender would have no feelings left for Ron at all.
Why Ron? Because when he kissed her, even now when they'd been together for five years, her knees got weak. Because he knew when she needed him to pound into her hard enough to forget everything, and when to whisper to her that they'd never forget anything, and when just to hold her tightly. Because it had been Ron who had beaten her to Harry's body and carried it back as carefully as if he might still be alive.
"Because I love him," she said, looking at Ginny. "Because you can't mourn forever."
