ISO Bucky oc fanfic

I’m looking for a fanfic that read a few years ago. I can’t seem to find it does it even exist I think it was on ao3. It was a fanfic that the followed catws and then went into civil war. What I remember was the reader/oc was also controlled by hydra they were partners almost but her and winter soldier were extremely close he was super protective of her and hydra used that another way to control Bucky. the story followed the catws movie and they were able to escape together. Or is there any fanfics the have a similar vibe?
