Made you look (слэш)

Being part of the Wakandan King's Guard was a job Bucky never thought he'd fall into. But apart from the uniform, it was a great gig, especially since he got to stare at Captain Steve Rogers when the changing of the guard occurred. The same Captain who six months earlier promised him the night of his life then disappeared, ignoring him after.
So when Bucky ends up on duty with Steve, he wasn't expecting to be recognised, nor was he expecting a rogue intruder to interrupt his less than platonic thoughts.
First save the palace - second get the guy?
Or was there some other plan in motion that Bucky didn't know about?
