The whole soul switching part is pretty interesting and the MC's backstory was very fresh to me since most characters especially FL's in Manhwa tend to be targeting a villainess instead of a villain. The story is very interesting and unique. I love the MC's way of thinking it reminds me of Medea from "Your Throne" and the MC from "Regressor Instructional Manual". Besides the story the characters are well written and very good looking. The smut is good and the ML and 2nd ML are great.
