Huge plot in the story is how many people are afraid that MC may become derange and start murdering everyone. Looking at how unstable and stupid he is currently, there is actually a possibility that story might take that path. Also because his followers hide a lot of stuff from him, it also might be a factor. Honestly, the more you read this, the more disappointing it becomes.
The biggest flaw in this novel can be seen in volume 6. So he gets an invitation to the dragon country to make a contract with a dragon (which basically means marriage to a dragon). He tells it to everyone and leaves to do just that. Then, after he gets to dragon country and meets the dragon he goes full retard. "Can I bring he back without the contract?", "Dragon, I have four fiances and I am not from your country, are you OK with me?", "I need to go ask permission to make a contract from everyone". Then he goes back with the dragon and basically says: this is the dragon, will you let me make a contract? I am not in love with her, but I am sure I will fall for her eventually.
Another stupid thing is that it is portrayed that he wants this dragon because she generates electricity. He says she is going to be so useful because of that. But it is super easy to make a basic manual power generator. Why the hell do you need a dragon to generate electricity? You can make basic power generator and even basic capacitors super easy. He also has scientists who can help him make those. It just doesn't make sense. The author just artificially inflates the value of the dragon chick to make her seem more important than she is.
And volume 5 is just an embarrassment and should not exist. It is goddamn awful and shows MC in the worst way.
So she meets the ghost of the noble girl adventurer who was betrayed, raped and killed. MC inherits all her knowledge and memories, including magic and martial arts. But apparently, for some reason, she still has to go to school? She doesn't know a lot of common sense, like what is a healer association. Why doesn't she have a theory about magic and weapons already? Why can't she do stuff that the nobel girl could?
And finally.... When that peach-senpai appeared... I stopped reading this sh*t novel...
One of the biggest disappointments for me was how Seoyoon started to speak. She was exchanging notes with MC because she was too shy one moment and then in the next paragraph she was working in a restaurant talking to a bunch of strangers. WTF? Huge deal was made of how she was able to communicate only with him and then sudden jump to complete cure. Such a missed opportunity for a good chapter.
