"Your heartbeat sounds different," Bucky declares suddenly one night while they're watching Star Wars. The declaration hadn't been accusatory but it was close; like it's not Steve's fault but in a way it kind of is. Contains m/m relationships, lots of Stucky fluff, cuddles, and a fair bit of angst. Enjoy!

Maybe the secret of Steve's desire for Bucky was imprinted on his genetic code, and like every other imperfection stamped there, Erskine's formula wiped it out. Bucky almost hopes this is the case, because the alternative is too painful to consider: that Steve simply stopped wanting Bucky of his own accord. (Stucky)
