Eighteen years ago, Su Nan was "accidentally" sent to the remote Wutong Town due to a family power struggle, and lived with half a box of leftover mysteries. Eighteen years later, the old man of the Su family was critically ill, and she secretly returned home as a "distant niece", waiting for an opportunity to explore the truth behind her abandonment and the "accidental" death of her mother.
When she first entered the Su family, she faced the rejection of her cold father, hypocritical stepmother Liu Yuru, and her arrogant cousin Su Ya. However, when the Su family company fell into a financial crisis, she used her unique business insights to temporarily save the situation, which unexpectedly attracted the attention of Lu Shiyan, the president of the Lu Group. One person hides the mystery of his life experience, and the other holds business power. The two go from testing each other's business cooperation to working together to fight against the conspiracies of the Liu family and the Su family, and gradually fall in love in the crisis-ridden whirlpool of the wealthy family.
Su Nan relied on her wisdom to counterattack from the bottom, revitalize unsaleable business, expose the financial shady, and gradually take control of the Su family; Lu Shiyan removed obstacles for her and helped her track down the truth. In the end, the two not only uncovered the real culprit who framed Su's mother and cleared the grievances of the deceased, but also integrated resources to build a business empire. In the process of inheritance and rebirth, they fulfilled the fateful promise of "Phoebe at the right time".
