Imagine...
Putting a sticky note on Bucky's arm every morning to give him a complement. You two are only friends, and he still wonders to this day how you get in his room, let alone his apartment every night to do just that.

Bucky is not a morning person. Not in the 1940's and definitely not now. He hated everything that had to do with mornings. Well, I take that back, almost everything. Just like the past few months, Bucky reached his human hand over to the shoulder of his metal arm and unattached the sticky note from above the red star.
Sneaking up on an assassin is hard, and doing it while they're asleep is even harder. Bucky still wondered how you'd get in, but what made him even more curious is the face that you of all people could sneak up on him in his sleep.
You snore in your sleep, and it is adorable :)
