Winterwidow Highschool/college Au's

Their past (IMPORTANT)

Basically is the story that explains their past. I will have a couple different background stories and at the beginning of each au I will tell what background it is.

Red Room background 1:
In 1943 Bucky fell off the train when he was 18 and Steve was 16. When hydra found him in the ravine they took him and made him into the winter soldier with the metal arm. It is now 2014 in the Red Room. The WinterSoldier taught the girls fighting. Natalia Alianova Romanova, caught his eye. She was the best fighter and dancer there. Every few days he would be put in cyrofreeze, for a week to a month at a time. Hydra only took him out when they needed him. Natalia grew fond of him and when they were alone she wasn't scared. She would actually call him 'Soldat', she can look past those steel blue eyes and see a ting bit of joy when she call him his nickname. But, she can also see all the torture and death in his eyes. It pains her. It pains her to see the only person she cares about besides her sister (yelena) in pain. After the graduation where the black widow and the crimson widow were born, they were to be the deadliest weapons in the KGB. Combined, they were almost as dangerous as the WinterSoldier but he was the most dangerous weapon in the world. Everybody feared him except Natalia and sorta Yelena. He worked with hydra so they didn't see each other much. A month after graduation he just disappeared. She thought nothing of it cause it's not like she had feelings for him. Or at least that she would admit. It had been 4 years since he had disappeared. She is now 20 and he is 22, well looks 22. He is most likely in his 90's. On one mission, she and Yelena faked their deaths and ran into nick fury. Fury quickly took them in when he found out who they were. He also said that they need to go to Mar-Vel University. It's a place for enhanced individuals. Ranging from hand to hand combat to super powers.
