I want to see Bucky tring to get used to a normal life once again, either in Cap's apartment or with the other Avengers.

The main issue to solve? Bucky's apparent aversion/starvation for any gentle human touch (that he's used to react to with violence out of self-preservation or fear).

I could have just said I want him to get a hug, but that would have been too simple and angst-free. :D
