I have this headcanon that all the guys on Team Mustang like have this low-key competition of sorts to earn Riza’s approval and praise.
Like it started really simple, one day after a long meeting Havoc puts a cup of coffee in front of Riza coz he can see she looks tired, and she gives him this lovely smile and the rest of the gang are like “so pretty. how can I get her to smile at me?” So it becomes this challenge to get Riza to smile and give out praise. And they’re all doing little things, like Breda sometimes buys her a sandwich when he goes to get his lunch. And Fuery brings treats for Black Hayate, and helped fix Riza’s phone when it breaks one time. And Falman is there with random facts that he knows Riza will find interesting. And then the Elric brothers come along. And Alphonse is super sweet all the time, and one day they’re in the office and Riza is in civilian clothes (as it’s her day off and she popped into the office for a minute) and Ed says she looks really pretty, and she thanks him and leaves. Then the others let the brothers in on the competition.
And Roy has no idea that this competition even exists. Until one day Ed compliments Riza, and she thanks him and gently ruffles his hair, and Ed, being the little shit that he is, smirks at Roy. Which is his light bulb moment. And Roy is in this state of shock as it all comes together and he realises that he’s been left out of it. So then he gets involved and suddenly there are seven guys all trying to get Riza’s attention and what was once a subtle competition has just exploded. And they’re all trying to one-up each other and it ends up getting really ridiculous.
Like one day Roy comes in and is like “I hear you enjoy bread sticks. So I got you these.” And pours this giant box of bread sticks on Riza’s desk. And Ed and Al are transmuting little figures of Black Hayate for Riza (like they did for their mum) and so Riza has all these little figures on her desk.
Riza of course realised what was going on rather early into the competition. But she acts as if she doesn’t know, because she knows it makes them happy.
