Every time Edward sees the circle on the back Mustang's hand, he wants to scream, wants to reach across the desk and shake him, wants to wrap his hands around the older man's throat and ask if it was worth it, if this desk and his rank is worth the screaming, crying, writhing, burning bodies of his people - "Something to say, Fullmetal?" Mustang drawls. Edward snaps the file shut, "Nope."

Everyone is born with the ability to only see the colour of their soulmate's eyes. Only upon touching their soulmate, can people see the rest of the world's colours. Edward Elric will do whatever it takes to get his brother's body back and ensure he can have his happily ever after with his soulmate, even if it means never finding his own soulmate.
