A/N : A little background into some of the terminology used in the story. There’s a hierarchy in Chinese crime organizations and they often go by numbers:

489 - the Dragon Master, or ultimate leader of the group (pretty fitting, isn’t it?)
438 - the Vanguard, or operations manager
426 - the Red Pole, or Enforcer
415 - the White Paper Fan, or financial and business advisor

A/N 2: Roulette terms:

croupier : Roulette dealer
rien ne va plus - ‘no more bets’
split - a bet on two adjoining numbers, either vertical or horizontal
street - a bet on three numbers in a horizontal line
 

I do plan on continuing this, possibly doing some backstories with the other couples.
