#bc Yata would be so mortified and Munakata so doting

[ridiasfangirlings]

Couldn’t get this out if my head - Brother AU where Yata and Munakata are half brothers. I just can’t get the reactions of everyone finding out. Like say during group missions with red and blue if it looks like Yata is about to be injured Munakata will jump in to be big brother and save Yata. Which in turn confuses some squad members to spark rumors of them dating. Cue Fushimi who has a freak out and doesn’t know how to ask if they are true or not. The stress gets amplified when Munakata tries to get lunch with his little brother cause that’s what a big brother does. And that since Munakata is the big brother he is allowed to call Yata “Misaki-kun” (Yata does not see it this way). Or that he’ll stop by HOMRA and Yata’s part time jobs to check up on him. It eventually comes to head when one member of the blues decided that enough is enough and that Yata should be more considerate other feelings and he should treat who he’s dating better. They rally the troops and go off to find Yata who’s walking around with the rest of the HOMRA crew and confront him. This leads to Yata having to scream at them that he is not dating their boss that would just be gross. Cue blue member asking back wants wrong with our captain anyone would want to date him. Yata feeling attacked bites back I’m not into incest that’s why before going red in the face embarrassed. Shocked and confused pikachu faces. Yata explains your captain’s my brother before leaving to go into hiding. The two squads part ways with everything making a little more since and when the blues get back they pass the information around that no the two are not dating and that they are brothers. Fushimi goes from relieved that Misaki is not dating he annoying captain to anxious that Misaki and the captain are related (Sarumi for the win...sorry). The blues now understand the relationship and the reds now have jokes like “you brother poached your boyfriend” or “hmm you better go say hi to your big brother” whenever they see Munakata out. Idk I just couldn’t get this idea and several others out of my head and was wondering your take on the different reactions of the two clans or how they all find out.

I am honestly very amused by the idea of the clans assuming Munakata and Yata are dating only to find out that they're related and probably thinking why does the idea of them dating suddenly feel like the more realistic one. Like say Munakata's always wanted to be a doting big brother to Yata but Yata's never liked him, like imagine by the time they are aware of the other's existence Munakata's already in high school preparing for college (oh maybe Munakata was the result of like Yata's dad having an affair before Yata was born too and he finally decided to leave Yata's mom for his mistress and so Yata also kinda dislikes Munakata for that even though he technically didn't have anything to do with it). Munakata never gets the chance initially to do much with his younger half brother, he only meets Yata like once before going to college and it's not until he becomes the Blue King and sees who the members of Homra are that he's very intrigued to discover his little brother has been busy in his absence.

Of course Munakata has always secretly wanted to be a big brother himself and now he's like determined to foster some brotherly affection between himself and his unruly younger sibling. Yata has no interest in this whatsoever and he also doesn't want anyone to know that he and Munakata are related because how uncool would it be for him as a member of Homra to be the younger half brother of the stupid Blue King. This does not stop Munakata from trying to be the best big brother he can be, which leads to moments such as Munakata noticeably stepping in to save Yata from being attacked by a Strain during some mission where Homra and Scepter 4 ran into each other, or giving Yata special attention whenever they run across each other (also he doesn't stop Fushimi from riling Yata up but maybe he keeps trying to encourage Fushimi in his own way to be more honest with his feelings, like a good big brother he wants to help his sibling find love too). He also refers to Yata within earshot of other clansmen as 'Misaki-kun' which is what really gets the rumor mill going, like did you hear the Blue King and Homra's Yata Misaki are on a first name basis with each other.

The Scepter 4 and Homra rank and file are soon all gossiping about it and of course Fushimi hears it eventually too. At first he blows it off as ridiculous but then imagine he hears Munakata call Yata 'Misaki' too and he's confused and irritated and doesn't know why the idea of this upsets him so much. Meanwhile imagine one day Yata runs across some Scepter 4 guys and he can't resist making some comment about their stupid King, the S4 alphabet are pissed that Yata could speak so cruelly of his supposed boyfriend. A few other members of Homra and Scepter 4 happen to be in earshot as the arguing progresses, the S4 boys thinking Yata needs to be ore grateful and is this how you treat someone in your type of relationship while Yata's mad thinking Munakata told everyone that they're brothers and that's the type of relationship they mean. He's like that guy's always smothering me and trying to act like we're close, the S4 boys are like so you don't even think you're close to the guy you're dating. Yata's immediately like what the fuck we're not dating we're brothers you sickos a moment before he realizes that no one actually knew and now he just told everybody his 'big secret.'

This of course opens a whole new can of worms for Yata, on the Homra side while no one questions his loyalty I'm sure the Homra guys can't resist teasing him sometimes about being 'the Blue King's baby brother.' The Scepter 4 guys like to use this to taunt Homra with too, like shouldn't you show respect to your vanguard's more successful brother. Fushimi is initially still a little bewildered by all this but I can totally see him using it as ammo to taunt Yata too, like noting Munakata got all the height in the family (and meanwhile Munakata's probably continuing to try and get the two of them to reconcile and finally admit their feelings, if only so he has an excuse to suggest that Fushimi also call him 'big brother'). Munakata only knows that Yata told everyone they're brothers so he assumes this must mean Yata has embraced the strength of their filial bonds at last and he's even more eager to bond as siblings should, poor Yata is like I should have just said we were dating.
