Six years ago, Nora, who had run away from her wedding, spent a single night with Lucian, the heir to a crime syndicate, during a rainy night, and later gave birth to their son, Liam, on her own. Six years later, Lucian hires Nora and Liam to pose as his wife and son to deceive his grandfather and secure his inheritance. The family elders secretly arrange a paternity test to expose the deception, only to discover that the child is indeed his biological son. Lucian’s villainous uncle and aunt collude with outsiders to kidnap the mother and son, but Lucian fights fiercely to rescue them. The two eventually marry, and the family is reunited.
