Partial spoiler, but the general premise here is that instead of hard drugs invading a poor innocent school, magic dice became the new heroin and all the cool kids are doing it. Interesting premise since these dice gamify the world in a believable sci-fi/fantasy sort of way as well as adding in morality dilemmas on top of it.
A big downside for me is how lazy the author is developing the story. Doesn't seem to have enough energy at establishing more unique character perspectives with these bizarre situations. A good example is the generalizing of "the mob" from the author and their actions during school wide events. Granted many would succumb to desires that would eventually ignore their already established morals, but not too many, heck maybe only a few. Many would probably just go for dice in moderation. But what would I know? I never took cocaine and I'm sure a few good who did, eventually did bad to acquire more, but not freakin most everyone.. right?
Probably nitpicking too hard but I had a hard time getting absorbed into this manhwa. Maybe it's because it's not going too hard into the game stats like The Gamer allowing the author to pull shit out of his butt to make the plot work at times. I understand he doesn't want to get tided down with the nuisance, but he keeps briefly showing these stupid radar chart character stats occasionally yet not frequent enough that we as readers still can't establish power levels between characters to any reasonable degree. Yes, I know this shouldn't be the focus of this manhwa, but as more chapters pile on, the more this becomes a battle shounen and the more this becomes a pressing issue.
EDIT: After reading up to chapter 186, my opinion has changed a bit. After you forgo stats and just embrace the vagueness of strength in this manhwa, it's much easier to move on and just see your fighters in simple letter grade ranks (B, A, S). This story's focus is less of fighting anyways and more of drama as it goes on. It all has to do with how characters handle these magic drugs in their lives. A large overarching theme is the question of what is the root problem, these drugs or the drug dealer?
