second doesn't fit just as much with what you're looking for, but it's a good read on LINE Webtoon.
There's also:

I’m looking for some recommendations with an under-dog plot. Kinda like an underestimated MC actually being strong or smart. Or an anti-hero one where the MC is morally vague and cynical. I’d prefer no romance but if it’s just a sub genre or isn’t mainly focused on the romance tag, I don’t really mind.
