[Crossover] The Iron Man’s Girlfriend

Molly Tardis's first boyfriend was a British detective. They broke up just as she was about to propose to him. Molly's second boyfriend was a wealthy man from Gotham. She firmly believed he wasn't a playboy and that he was a good person, but... they broke up. Molly never dated again, driving her childhood friend Tony Stark, who had been watching her like a hawk, absolutely crazy. A few things to know: The heroine is a completely ordinary person. The leads are not each other's firsts, but their relationship is otherwise exclusive. Everyone should know who the first two boyfriends are. The timeline is all over the place. It's a feel-good story, really. Any out-of-character behavior is my fault. The heroine's name comes from Molly in Sherlock and the TARDIS in Doctor Who. Theme:
