Fiona Shaw, once a privileged heiress, fell from grace three years ago when her family's business collapsed. Burdened with a staggering five-hundred-million debt, she was forced to accept the Sterling family's arrangement—an arranged marriage with their second son, Henry. Yet the union was nothing but a façade. Henry, a closeted man deeply in love with his loyal secretary Louis, had no affection for Fiona and abandoned her after their wedding night. His only reason for marrying her was to appease his mother, Elizabeth, and to secure an heir quickly—ensuring his claim to the family's vast fortune and strengthening his position against his half-brother, Jeff.

After her family is massacred by the Black Dragon Gang, the little girl Grace becomes the top assassin Dove. Now disguised as a mute, she infiltrates enemy territory, biding her time to avenge the victims. With lethal skills, she takes down villains but unexpectedly gets entangled with Jasper York, the heir to the organization she's sworn to destroy. When their paths cross, suspicion and mind games gradually give way to forbidden feelings. Caught between gang fights, psychotic killers, and deadly traps, she manages to balance her mission of revenge against her complicated relationship with Jasper. When her cover is about to unravel, can they join forces to bring down the crime empire?
