Love is an Illsuion

i've seen somewhere that recessive omegas have irregular heats and are often looked down on? don't take my word on it though, i'm not sure.

Imo recessives are closer to betas. Different mangas sometimes have different features of receives but in Love is an Illusion, I think recessives are less sensitive to pheromones and don't emit as much as their dominant counterparts. Also in the manhwa, they probably present a little later. In other manhwas I've read, recessives also have different body types like for example a recessive omega will look more masculine than a dominant omega and a recessive alpha will look more feminine than dominant alphas. Hence closer looking to betas.

This answer makes so much sense so thank you. (=・ω・=). It’s also backed up when it’s revealed that Byul is a dominant shown that he picked up his parents pheromones at such a young age. And in the beginning chapters when Dojin brought a male omega, this explains why he looked so feminine. He was a dominant! Thanks for your answer again even though it’s speculation ╮(￣▽￣)╭ . It upset me when I couldn’t find nothing on these traits on the internet.

Yes, the recessive-dominant concept isn't very common. Originally it wasn't even included in the omegaverse genre（￣へ￣）. It became a thing in mangas/manhwas not in western fanlore ( where omegaverse was created) so you won't find much on it since most information written about omegaverse is from western fanlore. Also that's why if you read a lot of fanfic (mostly generated from western media) on omegaverse, they feel quite different to mangas/manhwas.

oooooo ok (￣∇￣")
