⚠️ Warning: The MC is a scumbag and will stay that way for quite a while (No, I don't mean arrogant or selfish, he isn't). If you can't handle a protagonist who's disloyal, ruthless, and willing to do anything to achieve his goals, stop here. Don't expect a lovey-dovey or submissive character, he's the one in control, not the other way around.
That said, he isn't a villain. He genuinely cares for his people and helps others when it truly matters. As mentioned in my review, the MC won't be loyal to a single woman until he meets the true FL, and even then, you won't realize who she is right away. She'll be hiding in plain sight, so just sit back and enjoy the journey.
Note: This story draws heavy inspiration from Sword Art Online, Latna Saga: Survival Story of a Sword King in a Fantasy World, Solo Leveling, and Milf Hunter in Another World—particularly in how the MC interacts with and commands several powerful women.
The story includes NTR elements (the MC will steal or seduce married women), but there is no incest. Expect a decent amount of mature and explicit content, integrated naturally into the plot rather than being the sole focus.
