this is harem manga but all the girls a totally likable, unlike arifureta where only 1 is likable.. The best still the imouto type wife with a strange accent with good knacks on business

the fact that the dragon mother knows what is driving the world form behind the scenes and that certain things, like the lunaria religion and the cube that attacked the Dragons, seemed to be related to "our" world. As if the world is a sort of game or VR

For cotton thing yes if farmers hear cotton sells well and makes really good profit they gonna throw away other crops to plants cotton that realistic that what happens in real world too like people plant for money without any research later they regret because everybody doing same thing if no one plants grain and others no idea for that that kingdom gonna be really in bad sh*t for a time and others not gonna pay high for grain because that a grain not a cotton like you eat grain then gone but you can buy cotton then make something then sell for high price but for grain ? Even you make really good bread or something like that thats not gonna be expensive sadly (like you can sell cotton for 100g but you cant sell grain for 100g) I can say that author realistic with kingdom food problem but other than that meh.

For characters well you know what always happens one guy xx number girls nothing more male characters just sidekick nothing more MC gonna give it you all of them %100 he gonna conquer world with his mighty MAGNUM still MC brain person than fighting person so you gonna see always schemes.

Author rush start of this novel without anything happening then baam king gives title to MC then goes long vacation then princess comes like wtf dad then goes to MC then falls in love for me this is really cheap and sadly not original.
