"What?! The stupid mission requires me to wear the uniform?!" "Yes Fullmetal. You'll blow our cover if you don't." "And I'm being sent with you?!" "Yes Fullmetal." Edward Elric had been assigned on a mission. An undercover one. Him and Roy Mustang, Ed's superior, were assigned to go on the mission together. What they were supposed to do? Go to a party for soldiers, and Ed was supposed be Roy's 'girlfriend' Nothing could go wrong right..? Falling in love wasn't apart of the plan. Right.....?

Equivalent Exchange. The basic law of alchemy. It begins the chain of exchange. The passing of information, rules or even traditions. But that's not always the case. Roy Mustang needed stress relief. Edward Elric needed information. They make a deal. There's only one rule to this deal. Everything that happens, means nothing. Or so they thought.

Edward, Sergeant Brosh and Lieutenant Ross are all captured. When Major Armstrong, Lieutenant Hawkeye, Al and Roy go to save them, Ed is badly hurt. Mentally and physically. He won't talk about what happened. Roy decideds that its his job to fix Ed and over time, falls in love with him
