I finally decided to watch this drama. Villains are overtly vicious. Demon who we believe the worst evil ( No pun intended) can’t do much and seems too humane.
Then in the last couple of episodes, the priest revieled what he heard in a confession . This is an act which can get him excommunicated from the Catholic Churches elsewhere for good. So I am guessing it is another church that only Koreans go to worship. Any Christian priest would never reveal confessional details to another individual. Except maybe under duress to law officials under extremely exceptional circumstance. So I am thinking did the story teller did enough research on this story details . Is that why it’s a mismatch of most popular K drama’s shown before. It’s watchable. Nothing special. I always watch Kim You Jung’s dramas . She has the best chemistry with any ML that’s for sure.
