To raise money for her mother's medical expenses, Lily, who comes from a poor background, is coerced by the wealthy Chloe to take her place and spend the night with the drugged billionaire CEO, Alexander. Afterward, the sapphire token is seized by Chloe.
When Chloe unexpectedly falls into a coma due to a severe injury, Madam Vance forces Lily to wear a thick veil and marry Alexander in Chloe's place. Post-wedding, Lily’s rough hands, cooking instincts, and unique body fragrance successively arouse the CEO’s suspicion. While secretly visiting her gravely ill mother to search for a ring, Lily is caught by a tailing Alexander. The CEO finally realizes his wife’s identity is fake, and the scam teeters on the brink of exposure.
