These Paper Hearts (слэш)

Steve and Bucky have been orbiting each other their whole lives. When Bucky gets drafted to serve in the 107th, they end up on different continents and their worlds begin to fracture. They turn to letters in a desperate attempt to communicate to each other all the things they’ve never quite been able to say.
The only thing keeping Bucky going is the thought of Steve, who claims to be safe at home and working as an artist for the wildly popular Captain America stage show. Unbeknownst to him, Steve’s involvement in the show goes far deeper than sketching out posters and designing propaganda. As untruths begin to pile up on both sides of their correspondence, Steve and Bucky are forced to reckon with the all the changes the war has wrought on their lives, either learning to weather them together or else crumbling under the weight of everything they've left unsaid.
