I think I will check this one since I am fans of the Manga and Anime too. Anyway, have you guys see the Korean Drama Daebak( The Royal Gambler) or Jackpot in English? it has the same atmosphere as this Manga too since it's all about gambling and the stake was his wife. you're not gonna believe it but it has more lessons to teach us.
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.
