YES! SHE'S JUST AN AIRHEAD! SHE'S NOT A BITCH IN SHEEP'S CLOTHING! THANK YOU AUTHOR!
I don't really hate the heroine here, but that's mostly because MC never really cared about the prince or her status to begin with. If she had actually felt hurt by the heroine being an idiot or actually harbored feelings for the prince, it'd be a different story.
