In 2349, the top circles of Xingyuan City were disturbed by a business marriage. Su Qingyuan is the heir to a scholarly family who adheres to traditional scientific research. He is gentle and restrained but has the tenacity to refuse to admit defeat. Lu Shiyan is the business giant in charge of "Xingtu Technology". He is cold and decisive and manages the smart empire in an orderly manner. However, under the pressure of the family, he is in urgent need of a "qualified Mrs. Lu".
In a future city where smart butlers are common and virtual social networking is prevalent, the two become a couple in name only with a three-year contract. From the smart appointment communication when they first met, to the daily running-in after living together in the penthouse - the disagreement on the nutritional supplements in the early morning, the smart pick-up and drop-off after working overtime late at night, the tacit cooperation when dealing with family gatherings, and the unexpected hand in hand when dealing with the company's technical crisis. In daily life, the cold contract is gradually penetrated by warmth.
Social strife, business intrigues, and entanglements with old friends ensued. While testing and protecting each other, they finally saw the true heart behind the contract. When the convenience of future technology is intertwined with the complexity of human nature, this marriage that began with interests will eventually reach an unexpected ending under the starry sky.
