Rosa is an agent of S.H.I.E.L.D tasked with getting close to Tony Stark alongside her co-worker Natasha Romanoff to see if Stark would be a good fit for the Avengers initiative by becoming his and Pepper Potts' assistants. It isn't long before the plan is foiled and Rosa must get close to Tony simply by being herself. _ All rights go to Marvel/Disney because all the characters besides Rose in this fanfiction are theirs. All of the plot follow the MCU movies very closely except for some things I've changed to throw Rosa in as a character.
