Review Detail of JYGT in Reincarnated as an Imperial Prince

I love these types of stories, and although I frequently encounter plotholes in them, the authors try to minimize them in some way and create a coherent storyline that manages to reach an adequate ending. In this case, the author simply gave up after chapters 60–70 and simply decided to reach an ending no matter what: a plothole on top of the plothole, simply a disaster that is not worth reading, terrible development of the story and the world building without a plot, simply a disaster that is not worth reading!!
