Steve and Bucky were best friends, that was a given. But they were also soulmates, only Steve knew, not having the heart to break the news to Bucky. Luckily our favorite agent was on the case. -- Hello! This is a Soulmate AU. It's when if you're soulmate kisses someone else, or just generally gets involved with anyone you'll feel the pain. I'm trying to keep it with the plot of the movies, but it will probably drift off around Civil War. Sorry if that upsets you in anyway. This is a work in progress and is not complete, I'll update once I get some feedback, thanks for clicking! Thanks to @neriberii and @_Daughter_of__Hades because without them this would've never been published :) ALL CHARACTERS AND MUCH OF THE PLOT IN THE FIRST FEW CHAPTERS BELONGS TO MARVEL!
