In the stark tower. You and Bucky have always had this…tension between you two. Soft glances that linger a moment to long. Sharing a water bottle while training or cooking for eachother and making plates. Making sure he has everything hell need on a mission or he makes sure your rifles are clean and put away before you get them chance to. He’s gentlemanly and in return you’re caring and soft. The rest of the avengers see it clear as day even.
