I'm telling the world ~Sambucky~ Band Au

Pietro is in charge of whatever happens behind the scenes

Bucky and his band are famous, Sam was supposed to be a one time thing but they fell for each other. A few months into their relationship only the band knew about them, Sam wanted to go public, but Bucky says he isn't ready yet. Sam tries to talk to him, only to get shut out. He breaks it off, says he will come back once Bucky is willing to at least hear him out. Read to see how that goes.

Bucky still has his metal arm, but instead of it being from Hydra, its from an accident when he was a teenager. Sam designs and flys planes (like jets and stuff)
