Please do write fic for The Proposal I would gobble that up.
I'm thrilled to hear this because I went ahead and rewatched it this afternoon despite having absolutely watched it within the last month and now I, a person who generally approaches fic in any fandom as an opportunity to write romcoms, am taking this canonical romcom and using it as an opportunity to write some fic that's pretty insanely horny even for me:
“Andrew, come here,” she demands. She’s just a few feet away, and she wasn’t specific as to what she wanted him for. That must be why he doesn’t stand up when he goes to her. That must be why, instead, he crawls. Margaret’s legs are crossed, her hand on one calf as she unbuckles the black patent ankle strap of her stiletto heel. It’s taking some effort, her nails too long and the strap too narrow, the buckle too tight. When their eyes meet she stops, her hands falling away like she’s forgotten what she was doing as she sits up straight and looks at him. That’s okay, she doesn’t have to remember to do things. That’s what she has Andrew for. He waits, poised on his knees in front of her, for her next order.
