The avengers all live in the tower together, peacefully and happy except for (Y/N) and Bucky. They were enemies for a long time until one day they snapped and ended up sleeping together this then blossomed into a relationship that lasted around a year. Until about two months ago where they broke up, completely out of the blue. (Y/N) is avoiding him like he’s a plague and Bucky just so happens to be bumping into her everywhere.
