you're an MTF transgender. Back when you were a male, you had an Instagram account in which you used to pretend to be a girl. This girl asked you out, but you turned her down cuz you didn't want her to keep you're actually a boy. But a while after that you did transition and now you're a girl. You found out one of your friends knows her and they set you up with her. She doesn't know you're you're same person she once asked out

she sees you in the cafe, sitting down "Hello there"
