In this mangaka’s universe, yes
It's the first manga I've read that has this.
If we followed the concepts of others mangas he wasn't supposed to.
But every author has his/her vision
I think every author changes the rules i omegaverse universe according to the story he/she wants to write. For example, in 'love is an illusion'there is no biting. So maybe here the rules differentiate from the norm?
It's the first time I've seen this too.
most of them have at least one thing different to the rest. but most the rules are the same.
I'm hoping that an Alpha with a fated pair in this series can only sense the pheromones of other omegas during their heat but they don't get crazy about it unlike with the pheromones of His fated omega. I hope that's the case though because if not, It'll be quite troublesome.
Do alpha still get affected by other omegas even though they have already mated with their fated pair?
