Ah I really don't like the mc's character, I understand that a character development is supposed to be implemented (I hope so or I'm even more dissapointed if not) into the story, the mc being a not so good guy in the beginning, but I think that an mc, especially one who is a renowned legendary figure's descendant, should have more dignity and constitution (not his shitty skill).
I've read plenty mangas, manhuas and manhwas, and sometimes the mc had his childish, unpleasant moments, mostly for the comedic aspect of the story, but octher than that the mc is serious and focused when he needs to be, not pitiful like this at every moment. At this point (though I already noticed many times) I just think that this is a mirror to the original author's characteristics, or he's just a bad writer which I don't understand.
This manhwa is overall good, it has top-notch moments and it has these kind of trash aspects which appear in trash stories as I've experienced it already.
The original manhwa was not as good looking as this one, because not many can rival solo leveling's art style, but it differed from the novel, which to some aspects was a good thing, like not having these kind of trashy moments in the story and the mc's unreasonable behaviour, I think these aspects should've beenimplemented here as well.
It's not a bad thing if the manhwa differs from the novel, especially if the novel has its own problems.
