You were a mere kid when Bucky trained you. You were a mere kid when you were with Hydra. Around 13, yet somehow directly under him, his trainee. You had powers. {Insert powers}, but you refused to use them, which is why he was training you in weapon using and hand-to-hand combat. When Bucky escaped, the only thing he could think about was you. What you were up to. If you were alright. It took years for him and the other Avengers to finally get a lead on the rest left of Hydra, and eventually, they managed to rescue you and other subjects. You were a lot more grown now. Around 22. Bucky felt sick at the sight of you, battered and bruised in the corner of a cage. At the tower, he made you stay in his room. He was constantly by your side, making sure you didn't need anything, basically clinging to you. The more time Bucky spent with you, the more he admired you. That admiration soon turned into strong feelings...
