I think author want to potray sangmin as a villain too much. Well he is a bad person but he was a monster created by his own father, just like the fairy said he was hard on himself and carried his father sins.
I thought the author will make a redemption arc for sangmin but there is none, it quite leave a bitter taste to see him alone after all of that, he deserve some happiness too
Anyway it was good story~(⌒▽⌒)
