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 have also seen this movie, and I must say that one can have substantial insights after watching this. As per Manga and Animes, I am not really a fan but I am glad that I get to see that there are growing channels of satisfying each unique interest of those interested in gambling like us.
