This is a de-aged Ed and Roy story but I'm on mobile so I can't use that tag. And I wrote it with ATPD, who can be found on ff.net if you are interested in her works.Ed and Roy are turned into small children, and Ed soon finds himself with a second little brother. However, when they learn of their true ages, things get a lot more complicated, especially when they begin to remember their pasts. Parental/Nanny Riza and brotherly Ed/Al/Roy.
