hello! there's a fic where Bucky/tws and Steve have to pretend to be a married couple in a suburban town. I remember that they've sat at a dock before and they've also gone to dinner parties while undercover. they end up really liking each other in the end, I'm pretty sure! I just can't remember the title for the life of me. does it sound familiar at all?
I’m pretty sure you mean this fic:
this city bleeds its aching heart by Renne
The one where Steve and Bucky pose as a happily married couple while on a mission for SHIELD, to catch an international arms dealer hiding in a suburban neighbourhood.

It didn’t escape him that Steve shared his assumed last name. “Are you gonna be my cousin?” Bucky asked dully.
Steve frowned. “Husband, actually,” he said easily, holding up his left hand to show a typical golden band.
Bucky scowled and closed the door.
AKAAn AU in which Bucky is put in the witness protection program and Steve is the agent hired to protect him/pretend to be his husband.
And I honestly can’t believe I forgot this one!!
