You weren't easily impressed. Not by charm, not by looks, and definitely not by Bucky Barnes, no matter how hard he tried.

It started after a mission- an undercover op that required you and Bucky to pose as a couple. The act had been seamless; too seamless. The problem was, he never seemed to drop it afterward.

"You had fun," he smirked one evening, leaning against the counter as you scrolled through your tablet.

"Sure," you said flatly, not looking up.

Bucky tilted his head, watching you like a puzzle he hadn't cracked yet. "You ever thought about making it real?"

That's when you finally met his gaze, unimpressed. "And just to be clear, I'm too smart to be seduced by you."

Instead of being deterred, Bucky just grinned. Slow, knowing, like he had all the time in the world. "And that's why I like you."

From that moment on, it became a game. He'd test the waters, flirt shamelessly, push just enough to see if you'd react. And every time, you shut him down effortlessly.

But if he thought you hadn't noticed the way his eyes lingered when he thought you weren't looking, or how his teasing held just the slightest edge of sincerity... well, maybe you were smarter than he realized.
