Wanting to kiss him and smack him upside the head was the most Ron feeling in the world. She took his face in both of her hands and kissed him, as much to stop him talking as to seal the moment.
"Ronald Weasley," she pulled back, removing one hand and just cupping his cheek. "I want to marry you because I love you, not because some future me loves you. I love you, and I want to be with you, and I don't need to wait anymore."
She let go of him and picked three long strands of grass. She waved her wand, braiding them together into a band, before transfiguring it into gold.
"Ron, will you marry me?" She held the makeshift ring out to him. They could find better ones eventually, but somehow this seemed fitting.
