This is the first omegaverse I've read that includes rare recessive omegas and dominant alphas...hyesung is a recessive omega I guess that is supposed to explain everything...he is mentally slow he is incapable of making logical decisions unless he can make it a math problem...a maybe the creepy megane alpha will inadvertently help him with that.
Incidentally he would have to have this recessive gene from both his parents in order for it to show itself in him which means his dad had some self hate going on in his treatment of hyesung's mom and hyesung. Now hyseung has the self hate going for himself since he went from alpha to omega in an instant.
So there you have it. Self hate and idiocy
Every fucking time, I've said it before, and I'll keep saying it, this omega has one of the worst ever personalities in a yoia anime. Why is he so naive? Why does he continue to lie to himself? He has an opportunity to even though he isn't in "love" with the alpha, live a happy life with him and their baby. He keeps running away from his best option , he's extremely arragont, self-centered and overall has a terrible outlook on life. By now knowing his own circumstances he shouldn't be making these mistakes. And no one bullshit me about him being an omega and that's why he behaves like that, that's a load of crap, he is irresponsible and never properly thinks through his decisions. How could he possibly think that dick head could "protect" him http://www.mangago.zone/read-manga/love_is_an_illusion/uu/love_is_an_illusion-chapter-40/10/
