Heavy is the Head That Wears the Crown is my Historical Royalty Omegaverse AU where Chuuya is in an arranged marriage with Dazai, has magic, is genderfluid, and has to hide it all to survive in a toxic unsafe kingdom - starting as enemies who want nothing more to do with each other, they pretend to be a happily married couple until they actually fall - and they fall /hard/, but a war is looming and political tensions are rising, and while a happy ending is always guaranteed, it may not be the one they originally desired;)
