I agree this first chapter is pretty rushed, it actually looks more like those chapter 0/Promo chapters of other manhwas rather than a proper chapter 1.
That being said I've already finished the novel (first time I can say this about any manhwa 😂) and I can say it is a really good one, one of my faves, though we'll see how it'll go here. So far, I'm not a big fan of the art style, it was better in the novel, here they kind of seem more childish, but I'll continue reading to see how they'll adapt it.
thanks for the work!
