bucky barnes tells sam he has a girlfriend. he does not have a girlfriend. unfortunately, sam wants proof. fortunately, you happen to walk past at the worst possible fucking time. so bucky does the obvious thing. he kisses you. one fake kiss later and apparently you’ve been his girlfriend for weeks. now he just has to convince you to play along. should be easy. except bucky was supposed to fake the relationship. not start actually liking you.
