Still confused by all the different types of oaths.
Somehow the evil princess can control people with all these oaths without drawback, if that were true wouldn't someone have used that power a long time ago to control a lot of people.
I get the oath on the the male lead is insanely powerful, and locks him in, I am ok with it being that way with one person. But she seemed to be using a different oath to control a lot of people but from the description of the oath that didn't make sense to me.
