EdWin

Edwin is the het ship between Edward "Ed" Elric and Winry Rockbell in the Fullmetal Alchemist fandom.

Canon
Ed and Winry grew up together, as childhood friends and neighbors. Winry was very worried for Ed when he lost his arm and leg, and helped perform the surgery to give him automail limbs. She then became his automail mechanic, and whenever Ed needed maintenance, he would go to her, or she would go to him. Ed confided in Winry about how he felt that Alphonse resented him. Other characters would tease Ed about Winry being his girlfriend. Winry starts to develop romantic feelings for Ed a little ways into the series, and it is implied Ed had a crush on her before. At the end of the series, he proposes to her and she accepts. In the Brotherhood anime epilogue, they are seen to have two children together.
