Review Detail of Nimmipoo in Fey Evolution Merchant

A good World background. Development of the plot is steady and not too slow or fast. A smart and calm protagonist who can think with his brain instead of his d!ck. And no trashy young master cliché yet. The protagonist has a younger sister who is a genius but it doesn’t seem like she will be taken away by a powerful force to be engaged to some ultra super duper trashy young master only for the MC to show up and kick his A$$. Basically a good story without lots of crap n cringe. And it doesn’t seem to be harem too....atleast for now.
