Five years gone. Now she's back, and working with the one man she never forgot. Tim Bradford x OC Not following the series but using some key events

Sixteen Years Ago, Tony Stark and Pepper Potts had twin girls, Andrea Marie and Melissa Jane. Not long after the twins' birth, Tony and Pepper separated. Unable to be around each other, they decided that the best thing to do would be for them to each raise one of the twins. The twins grow up on different sides of the country, completely unaware of the other. One day while on a class trip in New York, Melissa and Andrea run into each other. They end up hatching a plan to get their parents back together: Switch places, find out why they separated, find a way to get Pepper back to New York, and get them to fall in love again. Shouldn't be too hard right?
