Ok so the fic I'm looking for is actually part of a Time travel/AU 'verse where Bucky from before the War and Winter Soldier Bucky switch places. The main story actually focuses on Captain America Steve and Bucky's relationship but I keep thinking about the 1st story that is told from Pre-serum Steve's pov as he helps the Winter Soldier and gets totally pissed off that someone has hurt his Bucky. Is this ringing any bells? I think I maybe read it on LJ - can't find it on AO3 at any rate. Any help would be much appreciated!
