The mission for Junhee and Byeongkwan was simple. Get into the exclusive illegal gambling club, Opulence. Seduce the ringleaders, earn their trust and then take them down. That job isn't so easy when the government is being paid off to protect the club or when personal feelings get involved. Falling in love wasn't part of the job for either side. Rin and Chiyo were willing to do whatever it took to protect the life and family they had built. Will two new members to their illegal gambling club steal their hearts or will the girls see through their facade and beat them at their own game?
