This, surprisingly, Draco felt he was ready for. "Astoria," he said again, and then a moment later he was, if awkwardly, moving so that he up from his seat - and then on one knee in front of her chair. Albeit, on the side behind the table, hidden from view. They may have only been muggles, but Draco had his limits and getting on his knees in front of anyone but Astoria was certainly one of them.
He took the ring from the table and opened it, and he was surprised to find that his hands shook a bit until he focused and they stilled. This, he'd prepared for.
