I am so very into the more dystopian kind of omegaverse, where the characters are Not Enjoying what's going on. It doesn't have to be dark, necessarily, but there has to be some kind of focus on the concepts of nature vs nurture/instinct vs reason + all the gendered dynamics that can exist in omegaverse stories, be it a retracing of IRL issues or an exaggeration for speculative purposes. Honestly though, incest in omegaverse stories hits so hard. I will one day write that fic with omega!Sanemi that has to hide his heats whenever Genya is around. Or that one MakiMai with the twins bonding in the womb... hopefully soon
