Gu Mo, the richest man in Jiangcheng, is a man who has turned the business world upside down. He is famous for his coldness and abstinence, but in fact, he is bent on finding the girl with whom he made a promise to "become a family".
Jiang Xi is smart and insightful. He works hard in Jiangcheng, just to save enough for a down payment and own a "home" of his own.
Due to an unexpected mistake, the fate of the two people intersects. Gu Mo discovers Jiang Xi's design talent and takes her under his wing against all odds.
Jiang Xi's talent aroused jealousy, and he continued to fight openly and secretly. Mr. Gu Mo protected her with thunderous means, and his indifferent protection quietly touched the heartstrings.
Just as the relationship was growing, the Gu family was suddenly in turmoil, and Gu Mo was forced to consider bidding for friendship with the Zhao family.
At the critical moment, Jiang Xi emerged with talent and tenacity, helping Gu Mo stabilize the foundation of the Gu family.
The storm subsided and the truth was revealed: Jiang Xi was the separated daughter of the Zhao family, and Zhao Yiran, who was thought to be the daughter of the family, was actually a fake daughter mixed in with her mother (a doctor) forging DNA. She had been plotting against Jiang Xi for many years.
After going through many twists and turns, Gu Mo found the person he promised back then, and Jiang Xi also found his true destination. The two fulfilled their long-delayed "family" promise.
