One word: hit or miss. Truth be told, non-human MC stories are harder to judge because the protagonist isn't bound by human morals, yet watching them violate those morals can still feel uncomfortable. I'm not saying that's the case here specifically, but look at famous non-human MC stories like "That Time I Got Reincarnated as a Slime" (less uncomfortable since the author keeps the MC pretty human-sided), "Re: Monster," or "The Death Mage Who Doesn't Want a Fourth Time"—the moral complexity in these can definitely make some readers uneasy. So this manhwa falls into that "you either like it or you don't" category—it really depends on the person. That said, what I've read up to chapter 67 is very well written. The art style might not be the absolute best, but it's definitely excellent quality, and the plot moves forward like a horse while taking some genuinely unexpected turns. I haven't found anything problematic with the world-building or execution, and my overall impression is very good. If you're bored of princess love-story soap opera manhwa or the usual tower-and-dungeons stuff, give this a shot—it won't waste your time.
