It is not been delusional, it is been practical. The prince's record with women who offended him has been severe except Feng Wu and Zuo Quingluan. He does not kill women but always makes his subordinate to degrade them and when discussing her offence he behaved as if he was unable to bear reprimanding her so it was left for his subordinate, the actions of the male lead are indecisive and childish.
