Jean loves Mustang's mischievous thinking.

(btw this is probably my favourite funny scene in FMA)

"Aye (Y/N), How about another round?"

"Alright, whatcha got for me?"

Roy Mustang asked you with a mysterious smirk on his face. You loved making bets with him because of how boring it gets at work- but also to see what the winner gets. It's all usually small but hilarious things like how last week you made a bet stating you could withstand the longest time with Mae Hughes blabbing on non-stop about his daughter.

You gracefully won that round and your prize was having Roy pay for a full body massage treatment- with extra nail and hair procedures too. The loser; Roy, as punishment had to stay with Hughes for a whole two days listening to him talk about how amazing Elicia and Gracia are.

This time he watched as you got up from your seat in his office and sauntered your way over to him- grinning at the thought of having more fun with your best friend. He leaned over on his desk and crossed his arms together with a brow raised in a playful manner.

You gestured for him to continue and you listened with opened ears and a grin on your face.

"I bet you, that I can find a date first by the end of today."

Your brow rose in question- pondering the bet and before you could ask, Roy already beat you to it.

"If I win- you are my personal slave and will do whatever I want, whenever you want."

You chucked at his answer while thinking about how conceited the Colonel was, just like he was in all of the bet's he proposed. You leaned over onto the desk and switched your weight to your other foot.

"Alright, Alright cocky Colonel- what do I get when I win?" You replied- emphasising the 'when.' The Colonel simply chuckled again, rubbing his chin in thought before he finally snapped his fingers in your directions. You would've been half way out the door if he did that with his gloves on.

"Yes! If, and I mean If- you win, You will become the unofficial Colonel for a whole week. Oh, and there are no rules- just like usual."

You beamed in happiness and clapped your hands in glee. Every time you had gotten caught trying to sit in the Colonel's chair he just happened to pop up out of nowhere and scare you- causing you too jump and fall onto the floor. You smiled evilly, thinking about all of the new things you could do when you would be sitting in that chair and ordering people around.

You extended your arm out while the Colonel stared at it, smiling as he also reached his arm out to seal the bet.

- Time Skip -

After three hours you now had no idea where Roy Mustang was but you guessed he was a some random bar with some sleazy girls so that he could use his smooth moves on them.

During that time you had been getting dolled up and making yourself look just about irresistible enough to score you a date but very surprisingly enough and quite sad for your ego- some guys had actually turned you down!

That's right! Men actually said no to you, how was this happening. Dragging yourself through the quiet halls of the Central Command Centre, you kept thinking about the bet.

Uh Huh! You knew exactly who wouldn't say no to you! The one and only Jean Havoc- that man has been flirting with you non stop, of course with his smooth moves you couldn't help but flirt back so that was a clear indication that he would agree with you.

Making your way into the mess hall you found, you fixed your hair over your shoulders and entered the hall, finding the blond haired man and sexily sauntered over to him- immediately catching his attention. The cigarette in his mouth fell out as his jaw dropped at the sight of you.

You confidently giggled at his behaviour and when you reached him, you sat across from him. You reached over and shut his mouth with your finger and smiled at him, "Don't wanna catch flies, do yah.. Havoc..?"

He began blushing and picked up his cigarette in a quick movement, you watched him as you arm was on the table with your head resting on it and then you asked the question that would leave you the winner of the bet.

"So.. Jean, I was wondering if you wanted to.. Have some fun and maybe go on a date? This Friday night alright wi-"

"Nah, I'm alright."

You were silenced by Jean's voice and you almost gasped out loud. You were sure your face showed pure shock and this time you knew something was up.

"Jean.... What did Mustang tell you." You growled out- all your happy attitude gone down the drain. Along with your ego.

Jean took a glance at your face and his relaxed expression was replaced by a scared one- already aware of how much your punches hurt.

"H-he said you would a-ask.... for a b-bet."

You growled in frustration. Of course Mustang would play dirty- hell he is probably paying some innocent girl to date him for the bet. Obviously he can't stand losing to you, it would hurt his self-esteem and reputation too much.

"B-But! U-uh... There d-doesn't have to be a-a bet for us t-to go on a d-d-date..?" Jean rasped out with blazing red cheeks. You smiled at him- your own cheeks and ears turning pink at the man in front of you as you nodded silently and walked away from the man, leaving him smiling and watching your behind as you walked back to Mustangs office.

Entering the room, you saw Mustang sitting in his chair- the one you were sure you would be sitting on when you won. Sadly that wasn't the case. Mustang held out a piece of paper towards you and you rolled your eyes already knowing what was on it.

A woman's number he managed to get a date with. You slumped into a chair, not looking into Roy's smug face when you spat out, "You play dirty Roy."

Roy simply continued smiling that devilish smile that you avoided seeing and he replied, "There are no rules, (Y/N)."

You turned sharply to look at him- eyes wide, realising he used your own words against you and bit your lip to stop yourself from saying something you would regret.

"And now, here is your new uniform- embrace it and enjoy it. You're dismissed."

Roy then got up and handed you some clothes, confused, you took it slowly and then walked to the door where he was waiting for you, holding the door open. His smirk made you somewhat nervous and you almost screamed when you got home and saw your new clothes.

- Time Skip, Next Day -

It was now the early hours of morning, getting up and eating breakfast and then to put on that skimpy uniform- you were cringing the whole time. The disgust never left your face when you thought about having to be the personal slave of Roy Mustang.

After getting ready, you were now headed into the Colonel's office where you heard other voices- most likely Roy and his other subordinates. You opened the door slowly, meeting the faces of Kain Fuery, Riza Hawkeye, Vato Falman, Jean Havoc and Heymans Breda. The men became a blushing mess as Roy Mustang chuckled at the sight of you wearing a tight blue jacket at showed too much cleavage for your comfort and tiny blue miniskirt that definitely complimented your long and smooth lags.

You couldn't show weakness to the man since losing was already defeat enough- so you just had to put up with it and continue work like nothing had happened. Besides it was only for a week..

Walking in to take a seat you were met with the sight Riza sighing with eyes of pity and then Jean who had a bleeding nose and his cigarette falling out of his mouth. With his eyes stuck on you he clumsily swayed over to Roy who watched you and your legs with a pleased smile.

"You're a miracle worker Mustang, I'll follow you for the rest of my life."

"Yes!"
