Together Again (FullMetal Alchemist)
Ed, Al and Winry used to have a best friend named Erika, but one day she completely disappeared. Ed had to find her. Years past them and so much had happened, that's when he met her again. But he thought she was hiding something from him... She had a secret she was too scared to reveal... EdxOC, WinryxOC, AlxMei, RoyxRiza, LingxLan Fan (some are only hinted)
Author's Note (4th August 2014): Yes I know there are a lot of grammar mistakes and whatever, this is one of my old works I'm working on fixing it, though, okay?
