Review Detail of XxEagleNightxX in The King's Mandate: Anomalous System

I stopped around 60 or something (it was really good) and I'm planning to read it again then I saw the title has changed and even the synopsis? Well, I saw the tags of multiple love Interest, beautiful Female Leads (with an s) and lastly polygamy. So is this harem. I'm a harem fan so it would be great if it is.
