At her birthday party, Ning Nuannuan is betrayed by both her fiancé and her best friend. By a twist of fate, she stumbles into the private world of business legend Gu Jinnian. He recognizes the disgraced heiress as the girl who gave him a blue umbrella in the rain three years ago, and proposes a marriage of convenience. He needs a respectable married image to secure his family’s inheritance, while she needs his help to reclaim her family fortune.
When Ning Nuannuan moves into Gu Jinnian’s mansion, Jin Garden, she discovers that the man the outside world calls cold and ruthless will make her hangover soup in the middle of the night, remembers every food she can’t eat, and even holds her hand all night when she has nightmares. Gu Jinnian, too, is surprised to find that this seemingly fragile girl can memorize all his business associates’ preferences and pinpoint the right acupressure points when his stomach hurts.
As they join forces to investigate the truth behind Ning Nuannuan’s mother’s death, they gradually discover that fate had laid the groundwork for this marriage of convenience three years ago. When Ning Nuannuan is kidnapped, Gu Jinnian risks revealing the combat skills he has kept hidden for years. When Gu Jinnian is framed in a business scandal, Ning Nuannuan uses her artistic expertise to expose a famous painting as a fake and turn the tables.
From pretend embraces that turn real to trust sealed through life and death, the day their contract expires, Gu Jinnian drops to one knee on the top floor of the hotel where they first met. “Nuannuan, will you let me keep fulfilling this ‘contract’ for the rest of my life?”
