I also watched kaiji film before but not yet seen kakegurui since it's a series I might not able to finish due to time but during quarantine I got hooked in some KDrama also Like Itaewon Class, not gambling related but ambitious enough to try to risk in different investment platform. I will add The Royal Gambler list of to watch when I got some time.
Although it is not directly related to gambling, I agree that “Itaewon Class” is a good KDRama series. It is more on the business management, stocks and how young entrepreneurs gamble what they have to achieve their dreams. I think that we are all have something like that within us, don’t we? But of course, it is important to set limits to pause and reassess things once again.
