Summary:
Ed knew he was different. It wasn't just that he was smarter than the other kids or even that he had automail. No, it had more to do with the way people would occasionally look at him, like they were expecting somebody else. It was the way his mechanic cried the day she met him. It was the way his dad would sometimes slip – and call him Fullmetal.
Review:
This is also a on going story and it's also long with 38 chapters now and each chapter is pretty long. So this is a good long story. Ed is turned into a baby and adopted by Mustang and doesn't remember anything. This is a parental!Roy X Ed and it's cute and really interesting. It blends beautifully with fmab and having its own story line. Things are staring to get slightly interesting later on in the story. I've also found some one shots that the author made to go with the story called "A Home for A boy Named Ed" and also a second story about Alphonse side of things with a part that is necessary to read for the main story. Alphonse's story called "dear brother" is letters that Al wrote to Ed while they are apart and you don't have to read the whole thing just up until a certain part so you know what happens in the main story. But this story is awesome and written well, so go read it.
