You are one badass assassin. The deadliest one alive. You're also Steve Rogers' long lost younger sister. When Steve and the Avengers find you single handily taking down one of their targets, they invite you to live with them. You only agree because Steve is there and you want to be with your brother. You don't know Bucky is alive until you get to the tower. Bucky's been in love with you since the 40's. He would constantly beg Steve to let him marry you. Steve would refuse. You admit that you wouldn't mind being with Bucky since you've always felt something for him back. The only thing standing in yours and Bucky's way is, well, Steve. So what else can you do besides have a secret relationship and hope Steve doesn't find out. This takes place after endgame and infinity war, but Thanos never happened and The Avengers are living together. I do not own any of these characters (besides y/n) and they all belong to marvel.
