Confused!

he's a reincarnate of the devil. what he's trying to do is become the bahamut king but before that he was trying to recruit our fl. The fl is trying to help the ml become the bahamut king but she doesn't know he knows she reincarnated. im pretty sure this part of the plot is explaining why the royals of the bahamut are after him and why he's going to try to take over the kingdom.. this is only what i think where the plot is going uwu

Thank you!!
