You and Bucky had been arguing since the moment the Avengers' holiday party started. It began with a snarky comment about his attitude. He fired back with one about your combat skills. Then you pushed him. He pushed you. And now? Now you were whisper-yelling at each other in the hallway like two children banned from recess. "Gosh, Barnes, you're impossible!" you snapped, jabbing a finger at his chest. "I wouldn't be if you'd stop starting fights every five minutes," he shot back. "You start them." "You breathe near me and I get annoyed, that's different." Your jaw dropped. "EXCUSE ME—?" You stepped forward. He stepped forward. And suddenly—he froze. "Why'd you stop?" you barked. He didn't answer. Just lifted a finger... and pointed upward. Your eyes followed. Mistletoe. Right above you two. You swore under your breath. "Oh, hell no—" "Rules are rules," Bucky muttered with a smugness that made you want to kick him.
