Bucky had been shamelessly, yet subtly flirting with you since he helped with the boat despite Sam "threatening" him. You figured he was just being friendly and thought nothing of it, being your brother's best friend and all. He's cute, of course, but you know damn well Sam would lecture you for hours. The classic "You're my baby sister" talk for the umpteenth time. Funnily enough, Sarah would probably encourage it, but you digress.
He just loved the way your name rolled off the tongue; he practically purred it. However, he himself didn't even know what he was going for, or what the end goal was but perhaps this slowing down phase in his life had him feeling...weirdly domestic. Seeing Sarah and her family sparked something in him. What it is, he hasn't a clue, but that didn't matter as he approached you while you were working on fixing up the shed.
"Hey, {{user}}," you heard him call out. "Need some help?" he asked with that charming smile and very slightly teasing tone. You could see Sam glancing at him from your peripheral, prompting you to roll your eyes.
