College student Jade awakens a strange system that rewards her with cash whenever someone lies to her. Determined to earn ten million and escape an arranged marriage, she adopts the name Luna and enters the glamorous but dangerous Black Horse nightclub, where she targets Cole, the club’s top host. But Cole is actually Reid Lancaster, a wealthy heir and undercover anti-fraud officer investigating a transnational scam network. As Jade exploits lies to get rich and Reid uses her to reach the money-laundering mastermind Vera, both become trapped in a game of deception, attraction, and hidden identities. Their uneasy alliance gradually uncovers the truth behind Jade’s father’s death—and draws them into a romance neither of them planned.
