Everlong
"Breathe out, so I can breathe you in…"
It's like the last embers of a dying fire; sometimes buried under soot and ash, but still alight with an angry orange heat fighting to survive for just a moment more. That's the best way he could think to describe this feeling, not that he'd ever dare say the words aloud. Like those embers, these feelings of his were fragile, and too much prodding could cause them to crumble. But Harry knew that if he wanted to be reunited with Ginny (and he did, sorely), he'd have to find some way to express this feeling to her. So he tried.
As she looked at him, looking thinner and more bedraggled than he ever had, she almost laughed out loud at the way he stumbled over his words. This brave boy, unafraid to stare death in the face (for honestly, how many times had he done it before?) could not string together a proper sentence in front of her. And yet she knew what he was trying to say, because she wanted to say it too. She wanted to say how she'd almost died when she thought he had; how she'd missed him more than she thought possible while he was away, and how angry she'd been at his overprotective nature; how she wanted to go back to where they were and stay together until the end of time, if he still wanted her. But she couldn't, and he clearly couldn't, so she did the next best thing.
Placing a hand on his cheek, and reveling in the feel of him nestling into her, she looked deep into his eyes and hoped he could understand how she felt. Then, remembering that he was still in many ways a silly boy and hopelessly dim when it came to such things, she settled for kissing him. That, she knew, he would understand.
When they finally broke apart again, gasping for air, he continued to hold her close, as if afraid of never holding her like this again.
"I feel like I've been waiting forever to do that," she breathed.
