Review Detail of ResidentialPsycho in I’ll Come Clean! I Am The King Of Lolan!

This is a slice-of-life series focused on the MC being treated as a genius because he was a history buff or else lived through that time period before. The chapters only consist of flattery and shock regarding his comments, even though they aren't world-bending concepts and would've been possible to figure out enough without him. The MC is a mystery. Considering he's not personally familiar with anyone there, it looks like he traveled through time to the past or something. Since the series mentioned transmigration, I thought he went to a world in a book that described history of this other world, but one of the readers commented that "transmigration" is a mistranslation here. If he had memories of his future sent to the past, then he'd have more relationships with people. If this world is in a book, then he'd have his own agenda. Therefore, it looks like he's a history buff that just traveled back in time. There's no mention of a family, so I guess he wasn't reincarnated but just appeared out of nowhere. Although the MC cooks excellent food, the food is never described in detail. In fact, the setting of the world and description of the appearances of various things is never given at all. I initially thought it was set to a place like Europe in the middle ages since western names were used and the king was implied to only have one wife. Later, the king has a harem filled with many wives and concubines rather than mistresses. Aside from the setting and world background having no information, the characters themselves have no details either. A couple of people are described as old while the MC is described as young. There is no information about their races or how they dress. There isn't even any culture described at all. This series is incredibly passive. The system would have been its saving grace since it could've added a plot, but it still hasn't appeared forty chapters in. There is no plot, and there isn't any story development. No female characters appear in the first forty chapters with the exception of one of the king's wives and her maids. She appears once. With no story development, no plot, no character design, and no world background, there's nothing to expect from this series. Once you read the first chapter, you've basically read them all. They all flow in similar ways. I can't imagine what the author was thinking while writing this.
