[Stucky] The Deserter

Picking up from the ending of Avengers: Endgame, this is an attempt to fix the OOC characterization of Captain America without changing what happens in the movie as much as possible.

But because my memory of the movie isn't perfect, there may still be some changes.

An incomplete summary:

1. Steve made his choice. He became a thief and lost his future.

2. Peggy had a pen pal who never wrote back. No one knows who he was, but Daniel has his own theory.

3. The Ancient One said that worlds without the Stones would branch into unknown timelines, but she never said worlds with all the Stones wouldn't branch.

4. Steve took more than one dose of Pym Particles, but he only used one when returning the Stones.

5. Captain America's faith is freedom. Steve Rogers' foundation is Bucky Barnes.

6. The "deserter" has nothing.

7. Bucky will always love the little guy from Brooklyn, no matter which one.

Theme: Undoing a tragedy.
