“Promise me, Steve. Promise me you’ll give her a life we couldn’t have.”

GIFTED AU where Mary is Steve’s and Bucky’s daughter. And when S.H.I.E.L.D learns about the gifted child of the supersoldiers, they try all things possible to take her away from Steve, who’d given up on all to give Mary a normal life that he had promised Bucky he’d give her before Bucky had gone under.
