False Reputation by erimeows

Summary
Roy Mustang has never been so nervous in his entire life.
Below him, on his bed, is the most beautiful woman in the world- his girlfriend, Riza Hawkeye. It feels like a miracle, the fact that she's chosen to be with him after everything they've gone through and after everything he's done, but she has. And they're here together now, in his apartment, with half their clothes off and their bodies pressed together under the thin silk of his bedsheets.
It's perfect.
Or, it would be, if not for one thing.
The reputation he has as the biggest playboy in Amestris- the idea that people have of him as this charming man who can woo any woman into his bed in a matter of minutes, who spends all of his free time sleeping around- it's false.
And even worse than that? He's been lying to Riza about it from the very start.

Between Friends by erimeows

Summary
It’s a line that they’ve tip-toed far too many times, yet never actually crossed. It’s exciting. Thrilling. Havoc isn’t even remotely uncomfortable, just relishing in the attention from them while he can. It’s likely that, by the end of the night, they’ll wind up in their own hotel rooms- and in the morning, they won’t talk about the wanton looks or lingering brushes of their hands on one another.
“Hey, you two,” Mustang casually starts when the bartender announces that the bar is about to close for the night, his voice not betraying a semblance of what’s to come. “Why don’t we head back to my room for some more drinks? There should be more than enough in that mini fridge to go around.”
“With all due respect, sir,” Hawkeye, easily the smartest between the three of them, interjects after swallowing down a gin and tonic. Perhaps she, like Havoc, has noticed the stolen glances, fleeting touches, and boundary-pushing comments sprinkled throughout their impromptu outing. “Are you sure that’s a great idea?”
And, Havoc being Havoc, he foolishly laughs at Hawkeye’s words with a shrug and says-
“What’s a few more drinks between friends?”

If It Ain't Broke (Don't Fix It) by erimeows

Summary
“Lieutenant."
Riza hopes that he's merely addressing her to discuss something work-related, but knows that he's not based on how his features are slightly twisted with worry that he wouldn't dare let show with anyone else around. He has the most pitiful expression on his face; perfectly plucked brows furrowed, charcoal eyes full of genuine concern, rosy lips turned slightly downwards in the beginning of a frown.
“Colonel?”
“You’re not doing well,” Roy says. It's not a question, but a soft, calm statement that fills her with rage. Her first thought is fuck you, I'm never doing well anymore and we know it, so why do you even bother? She's just barely able to bite her tongue for long enough to let him finish. “You don’t… Need to tell me about it, but I’d like to make you feel better.”
Riza winces, because she already knows where this is going.
Every time that she gets into one of her depressive moods, Roy notices- and when Roy Mustang notices something, he can never just leave it alone, especially if he perceives it as a problem. Instead, he thinks that he has to fix everything, including Riza, no matter what it takes.
Today is apparently no different, but when is it ever?
