Y/n, Steve and Bucky have been best friends since they were kids. Bucky and y/n were, you could say, more than friends. They went to war together, they fought together, then Steve lost both of them (or so he thought). Y/n and Bucky were brainwashed by Hydra and turned into the Winter Soldiers - deadly assasins. Will they be able to fight it and save each other? Will Steve be able to find them, let alone save them? What will happen to their friendship/relationship?
