"I like you. So I've been paying attention." An easy shrug, in part because he knows that Sam knows that running is not the ideal move here.

Unless he wants to be chased down. Which... Bucky is wholly not against.

"It is a game, but I'm not playing for sport... mostly." Another shrug. "I play for keeps, Sam. This is not a one and done. You really should close the door," is all the warning Sam gets before Bucky more or less leaps from where he's standing against the desk, pinning Sam's back to the doorjamb. "Someone might hear if you don't, sweetheart."
