Y/n is Tony's sister and helps him out in managing a few things concerning the Avengers. When Natasha first lays eyes on y/n, she is captivated and developes a crush very soon. But she doesn't know how to approach y/n, especially because y/n doesn't seem to want a relationship. Can Natasha change that and win her over? Can she convince y/n to give them a chance? Disclaimer: I don't own most of the characters except for my own. the plot mainly belong to me but a few bits are inspired by Marvel too.
