Imagine sharing an apartment with bucky. One day you went grocery shopping, and while you were waiting in the line you saw an old (male!) friend from your old school. You chatted with each other and he asked if you wanted to have a coffee at his place. (You two were just friends :D) You happily agreed. After a while in his house the door suddenly broke down to reveal a really pissed Bucky. He looked like he was about to choke (old friends name) but you quickly excused yourself and dragged Bucky back to your apartment. You angrily asked what that was about and he looked down in shame, saying he was worried because you didn't come home. Your face softened and you pulled him in for a hug, telling him that (of/n) was just a friend.
