Fine Line (Bucky Barnes x OC)

Luna Woods joined the Avengers after they saved the world from Thanos. She was reclusive and liked her privacy. She did her job and she did it well. That was all that mattered to Luna and, in her eyes, that was all that should matter to her teammates. However, her partner didn't see it that way.

Bucky Barnes knew nothing about the woman Tony had paired him with. Luna was reckless and always tried to do everything on her own. She took needless risks and put herself in danger instead of asking for help. She didn't trust the team to have her back, so how could he trust her to have his?

When Tony sends Bucky and Luna on a two month mission that requires them to pose as newlyweds, it's a recipe for disaster. The two can barely stand being in the same room together and now they're expected to live together and pretend to be in love in order to accomplish their mission. Neither expects the mission to go smoothly, but what they don't expect is that this mission will change their lives forever.

As Bucky begins digging into Luna's past and unexpected feelings surface, will they be able to navigate the new dynamics of their relationship while fighting off an unexpected threat?

They say there's a fine line between love and hate, but neither Bucky nor Luna realized just how thin that line was until they've unknowingly crossed it.
