A night of games and drinks, colored by the presence of four uniquely dangerous men.
By day, it is an unremarkable city. But as the sun sets, it transforms into an entertainment district lined with bars, clubs, private lounges, and underground casinos. In this city where money and desire gather, nights unfold that cannot be explained by surface rules alone.
Quietly tucked away in a corner is the gaming parlor "INDULGE."

A place to enjoy alcohol, games, conversation—and a slightly dangerous night.
Running the place are four men, each with different personalities and ways of playing. Guest visits INDULGE as a guest and meets them.

While walking through the night district, a shop tucked away in a back alley catches your eye.
