MC is an actual anti-hero manipulative and scamming bastard with a broken moral compass that likes to take advantage of people. He lies a lot and his lies get so big to even start wars but he will never admit his lies and see it to the end, a very fun read. I just hope it's not a harem, but by the looks of it, it's going that way. Either way, it's really refreshing to see anti hero mc doing shit right.
Edit: oh my bad, this shit is a harem afterall
