This story is so fucking good dude. If you haven't yet, read this.
The MC is the obvious stand-out here, he's probably my favorite protagonist in anything ever(?) probably. Top 3 at least. I feel like a lot of stories try to do the whole 'smart protagonist outsmarts the antagonist' thing, but I've never seen it done this well before.
I love how they actually commit to the 'powerless protagonist' idea, way more than some other stories I've read. No exclusive abilities other than being able to read people very well.
99% of the time, the way the MC outsmarts people is very well executed as well. It's just so peak.
Not to downplay the actual plot, though, which is fairly interesting in itself. Small critique though, I feel it does lose a little focus later on, but that's hardly a complaint for a 200+ chapter series.
Overall, it's just so good, I can't wait to see how this one ends. 10/10
