This is definitely a rare gem. You can't truly can't trust NU's rating where decent novels get dump and tr*sh without proper thoughts novel gets popularity. I have been reading korean modern fantasy novels or the another world second chances but this is a really unique and interesting setting. A King of a advance magical country, dreams of being a man who is a laborer of a company but the twist is, it's all real. It is just in another world called Earth and the King is seeing his other self like a TV where he can see his daily life.
The story is on more the modern Earth man's side, where he struggles in his life and gets better while having supernatural power but not an overpowered one. He also doesn't know he is a King in another world and it is more on like The King is watching himself like a TV, getting frustrated and prideful whenever the other man makes decisions, and helping him out so he won't die since if he did, the other one will.
I got hook up of the unique settings and I must say, it's a well thought novel. Not all characters are evil or no illogical dumb decisions making. Just like you're with the MC sympathizing and relating on his situations.
