Of course, he's not perfecthe still makes some mistakesbut I make sure they don't cause any annoyance to readers.Side characters? Sure, they will have some depth.Harem? Don't worry. The MC is not a simp, and his girls are not stupid either. They build real connections; I don't just throw girls in and call them his wives.Fighting? A lot but it leans more toward tactics than just fighting over who has the better cheat.The pace of the first ~20 chapters is quite fast, but don't worry, it will slow down later.
