Yes, basically the priest is one of the three reincarnated person who was punished by God I think? In his first life he killed his lover so he was punished to kill the one he loves in his next life or he will die. And it's our FL correct me if I'm worng
Also The FL is a Cursed reincarnated to she must kill her child as to thats her sin. I forgot the third person.

Thank you for the update!

.... pretty sure priest is the one that tries to kill her because of that complicated plot thing but other than that he's good right???
