Su Shutong, as the true daughter of the Gu family who has been miscarried for twenty years, returns to the fragmented Gu family after her adoptive mother dies of illness and her adoptive sister plans to evict her. Faced with the dilemma of her father's serious illness, loss of property, and her stepmother and fake daughter joining forces to eat into the family business, she managed step by step with a calm and tenacious attitude - starting from saving the time-honored embroidery shop that was on the verge of bankruptcy, uncovering the land deed conspiracy hidden in the family's old house, cracking the commercial espionage planted by her stepmother, and in her cooperation with Gu Yan, the president of the investment bank, she developed a forbidden affection from the "alliance of interests" that exploited each other. However, Gu Yan's Bai Yueguang turned out to be the key figure in the baby swap that year. The fake daughter grew in love and hated her, so she teamed up with her stepmother to set up a trap. On the way to rebuild Gu's house, Su Shutong not only had to protect the dignity of the family, but also faced the misunderstanding and betrayal of her lover, and the sadomasochistic entanglement ran throughout.
