I've read some books like that, only specifically werewolfy type of omega, but never seen a webtoon like that
Several. You just got to search for them.
Although, not my cup of tea, I did stumble upon this one year's ago: https://www.mangago.me/read-manga/bite_maker/
only today im learning that omegaverse doesnt exist elsewhere
“love is fantasy”, same author as love is an illusion and it’s alpha female x omega male
is there an omegaverse thats hetero?
