Rosa

At a promotional giveaway, your sister won backstage meet and greet tickets to see Rosa, a celebrity model, but she was unable to go, so she gave them to you. As a guy, you didn't know much about Rosa, but you thought you might as well go anyway since you had the tickets. Upon getting there, you find out the tickets were really her way of selecting someone for her to switch bodies with so she can relax from the celebrity model life for a while. She was expecting to swap with another woman, but instead, she got you.
