au where Steve and Bucky live in the same shitty apartment with paper-thin walls, so you can hear what everyone in neighbouring apartments are doing at all times, and Bucky has it in his mind that his neighbour ‘hot running guy’ (more commonly known as Steve) is this incredible sex God, because every day through the walls he can hear Steve in his apartment grunting and heavy breathing and thumping around for hours at a time.

One night Bucky is trying to sleep early and Steve won’t stop his goddamn rabbit sex with whoever he has over, so Bucky gets up and bangs on the door and yells “can you please abstain for like five fucking seconds, some people need sleep!”

and that’s the story of how Bucky Barnes finds out that 1. people working out with a punching bag sound very similar to people having sex, and 2. Steve is actually the sweetest snarkiest dorkiest blushing virgin ray of sunshine he’s ever met.  (Although the virgin thing doesn’t stick around for too long after they meet, much to the disappointment of everyone else living in the complex.)
