It was a getting together post-CAtWS fic vaguely from Bucky's pov, the specific scene I can recall is: he remembers (or thinks he remembers) wanting/loving Steve before the war. When he asks Steve 'were we, did we ever?' Steve shakes his head and says no, but before Bucky is too disappointed adds 'but we wanted to.'
Anyone recognise this? It was probably on AO3, although there's a tiny chance it was on tumblr.
