lucky ones

After the Civil War ended, Bucky spent 5 months in Wakanda, doing therapy and trying to be fine. It didn't last that much cause T'Challa thought it would be good for both of them to have each other around.
Steve finally had his pal around him. After a long time, they were together as they used in their childhood. They're older now, a lot older than they expected.
Now they both understand feelings and how life works, where this journey might take them?
