beta
This MC can't be the crown prince because he's a beta, not alpha or omega.
This ML can't be crown prince since he's an illegitimate child, even if he's a dominant alpha.
That rogue prince can't be the crown prince since he's an omega, so he needs to pretend to be a beta.
Wth do people waaannntt????
Seriously glad ABO is fiction, otherwise cases of bigotry is gonna be tripled.
