Ron grinned, and held out his hand feeling only a little bit ridiculous. "Yes. Of course I will," he said, and let her slip it on his finger. Then, he picked three strands of grass as she had, forming it into an untidy braid. His transfigured ring wasn't quite as polished as hers was, but it would do now.
"There, now we match," he said, slipping it on her finger before tackling her to the ground so he could kiss her properly. "Harry is going to make so much fun of us, you know that right?"
He kissed her again, then moved them back into a sitting position, his arm around her shoulder. "When we do actually get married, I think we should keep it small. I mean, hard not to, but maybe just you, me and Harry, and then we can have a party or something. It'd feel weird to do the marriage spells without...well, without everyone. You know?" He sighed, pressed his cheek against the top of her head.
