This story would be so much better without the weird harem / polygamous marriage that is shoehorned into an otherwise fun adventure story about an Overpowered main character levelling up. Also fucking weird because the main character is basically still a child and the women are adults. Sometimes there are stories where you can just ignore the harem / romance and enjoy the other parts, this is not one of them. Dropping because it's so gross it ruins the whole story
