I haven't watch the drama because I read that the acting and the dubbing are not good, and the trailer doesn't look interesting. It's the very first concept trailer that makes me interested. It has no actors, only some shadows and some conversations.
Imo, omegaverse is mirroring some real life situation. For example it was divided into 3 + 1 categories; alpha, beta, omega, and enigma. In real life there's ace who's good at everything = an alpha, there's ordinary people who's average = a beta, and there's people who's also good at everything but because of limited resources, family situation, or accident has to become a homemaker (can be male or female). For enigma, I think it may mirroring an absolute ruler, they can change and do anything. I once read a manga mentioned that enigma is the king of omegaverse, just like a lion is the king of the jungle.
Just a thought.
And I prefer abnormal omegaverse plot. Like alpha with alpha, omega with omega, enigma changed alpha into omega, and omega topping alpha.
Hahaha
