Ning Nuannuan was betrayed by her fiancé and her best friend at a birthday party, and accidentally broke into the private domain of business legend Gu Jinnian. Gu Jinnian recognized that the distressed daughter was the girl who gave him a blue umbrella in the rain three years ago, and proposed a contract marriage - he needed the image of marriage to fight for the family inheritance, and she needed to use her strength to regain the family property.
When Ning Nuannuan moved into Gu Jinnian's mansion "Jinyuan", she found that this man who was rumored to be cold and ruthless would cook her sober soup late at night, remember all her dietary taboos, and even hold her hand all night long when she had nightmares. Gu Jinnian was also surprised that this seemingly weak girl could memorize the preferences of all his business partners and accurately find the acupoints to massage when he had a stomachache.
As the two team up to investigate the truth behind Ning's mother's death, they gradually discover that behind this contract marriage is the foreshadowing that fate laid as early as three years ago. When Ning Nuannuan was kidnapped, Gu Jinnian did not hesitate to expose the fighting skills he had hidden for many years; when Gu Jinnian was framed by business, Ning Nuannuan used her artistic expertise to see through fakes of famous paintings to save the situation.
From the fake hug to the trust of life and death, when the contract expired, Gu Jinnian knelt down on one knee on the top floor of the hotel where they first met: "Nuan Nuan, are you willing to let me continue to fulfill this 'contract' for the rest of my life?"
