Neighbor AU

On the third day of Christmas, Bucky gave to me, a key only for emergencies.

Grumpy x Sunshine vibes. This is more tailored to the FATWS Bucky. Metal arm, Grinch-y heart. What’s something yall would like to see for the 12 days of Buckmas? Any specific AU’s or storylines?

What’s in store for the fourth day? Here’s a hint: “You WILL go to the Christmas party. I’ll have something dropped off for you to wear.”
