Review Detail of precursor in Invincible Colorless Butler

Grammar definitely not the best. I find the concept of the story fairly interesting but besides that it can only be seen as cliche the characters are extremely shallow to the point where every character is basically the same character. For example any males in the story that are around the MCs age are extremely prideful and arrogant. They are always in love with the princess around them and always tries to beat down the MC which the princesses are in love with for no apparent reason other than the MC existing. Also all the princesses or members of the stupid harem are basically the same character or a cliche. Next the society in the Novel makes no sense, apparently everyone is basically fine with some random mediocre butler marrying a princess. Basically there is no noble society or any kind of political environment within the kingdoms, also there is no formality at all to the point where a king could casually make a meeting between Kings and address them in a light hearted and casual manner. Then there is no political consequences for any of their actions which doesn't make any sense. In summary this is just a decent concept but poorly written and poorly done.
