American Pie (Yelena Belova X Fem! OC)

Alexandra Maximoff, Alex for short. Had a normal life until she was taken from her family when they were at the park. Her family assumed she was dead after 3 years of searching for her. They were devastated. But, they assumed wrong. Alex was taken to Russia and admitted to the Black Widow Program. As years went on she got more and more lonely. Alex began to close herself off from everyone (i mean can you blame her). But that didn't last much longer because a certain redhead saw past the wall she had put up. From then on they became best friends. As time went in the red room went on they had become an inseparable duo, Dreykov saw this and had to put an end to it. He called his good friend Strucker and had Alex taken to hydra to be experimented on. The duo was broken. Alex was presumed dead. Again. It was "The day the music had died". What will happen when Alex is on the same mission as Natasha and her sister Yelena.
