Malcolm had no idea what was going on, but with every passing second he felt more and more eager and excited. If it was something Grey had planned for him, then he knew that whatever it was, it would be perfect. Everything she did was perfect.
She returned, and as much as Malcolm wanted to ask her what was going on, he accepted her kiss, and almost forgot for a moment that anything was going on. He could easily get lost, kissing her.
Then she opened the box, and Malcolm was sure that his heart stopped for a second. It was a ring- it was a ring- he felt warm and shocked and overjoyed and then it was quite clear that his heart hadn't stopped, quite the opposite. She was talking, she was proposing, and he wanted to cry and laugh with joy, he just didn't know how to react.
"Oh my God, Grey! Yes! Yesyesyes!" he exclaimed, reaching for her and pulling her into a hug, the box crushed between them for a moment.
