This is a story of a man named Kim Sae-Jin, who one day, inexplicably wakes up as a Monster. Follow him and his perilous journey to get his life back as a Human, all the while growing even more versatile as a Monster in the process. This should be… complicated, somewhat.
The story is best to read for the people who liked genre of leveling up strength with killing mosters like solo leveling. This fiction have mc with abilities of magic (wizard), crafting weapon, medical potions (alchemist), weaker to strong personality and strength, a buisness man, savour,romance, harem,etc. I am pretty much satisfied with the ending of the story. This is actually rare 'cause i don't know but many of the writers are unable to end story with happy touch. If author could improve his 'naming a character' ability, that would be good. There are just too many. 'kim' in the story.
