I read it so I could argue with you, but I hate to admit... It's actually ok so far. I like that betas actually exist in this one. I don't get why it had to be omegaverse though, why couldn't it just be class differences or something?
Also, cap this because as good as it may seem now, it'll definitely descend into the usual forced drama and pregnancy bullshit. The main guy will get turned on by an omega or his family will arrange a match, and he will be stuck between the beta he loves and the omega "his biology" wants him to dick. You'll see.
