At a critical moment, she reaches an agreement to marry Lu Zheng, the owner of a auto repair shop, with a monthly allowance of 10,000 and non-interference with each other. Escaping her cage, she studies for the college entrance examination while reorganizing the factory's finances. Lu Zheng appears rough on the outside but secretly leaves sticky notes and drives away her extorting younger brother, silently protecting her safety. Tian Xiaomai counterattacks and is admitted as a preschool teacher, and Lu Zheng tears up the contract, gifting her real estate shares. The two go from fake husband and wife to true lovers, finally fighting back together against their blood-sucking family.
