Stark's hidden shadow (Steve X Reader)

This is a redone version of a story I previously created, however, I ended up changing almost everything about the story. Anyway...

This is a story in which Allison Stark, Tony's daughter had been separated from him when she was little, due to his loss of custody, however, her mother proved to be an even worse parent when Alison was kidnapped while her mother was at the bar.
Alison grew up in the Red Room, though due to her power, she never went through the graduation ceremony because of her potential. Dreykov gave her up to Hydra once she turned 21, where she bonded with both the Maximoff twins and Bucky while he wasn't out on missions. Though after the nth time, she tries to escape, Bucky being the one to unconsciously bring her back, Hydra grows tired of her attitude, and due to their deal with Dreykov, they are unable to punish her, so they send her back. Nearly a year later, Allison is given the date for her graduation to truly become a black widow, and it is then that she finally tries to escape once more.
