Little Romanoff (Y/N Pov, Nat's daughter)

Y/N Romanoff was born in the red room to Natasha Romanoff and Dreykov. She gets taken away from Natasha when she'd enough to walk and talk, to be trained to become the best assassin the red room has ever seen.
Nat believed she was dead, that's what she was told. Natasha escaped the red room and left her behind.
A few years later, some of the Avengers go on a mission to storm the red room and find a 17 year old red-head, almost the double of Natasha at that age. They capture her and take her in.
She becomes part of the family, but how will she cope? what does the future have in store for her?
