Ron didn't want to let her go, didn't want it to end, but he knew that this wasn't exactly the time or the place for this. They were supposed to be inside, helping the rest and he didn't want to be the useless Auror who had nothing to contribute to the meeting. So he pulled back, rested his head against her forehead and sighed. "I love you, Hermione. There may be a lot of things going on in the world I don't know at the moment but I do know that for certain. I hope you know that."
He smiled a bit lopsidedly at her and rubbed her cheek gently, then kissed the top of her head. "We should go back in, yeah?"
