Su Zhi, a designer who died of overwork and sudden death, transmigrated into a true-and-false wealthy daughters novel, becoming a short-lived, vicious adopted daughter. Burdened by a system, her life points can only be sustained by relying on the core characters of the original work, and she would suffer sudden death if she is not careful. When kicked out of the Yun family by the door, she calmly accepts the compensation money from the family members, and turns around to cling to Huo Wujiu, the ultimate villain disguised as a delivery driver. Holding the foreknowledge of the complete plot, she deals with the troubles from the Yun family members and blocks the rotten peach blossoms coveting Huo Wujiu on one hand, while getting close to the villain in various ways to accumulate her lifespan on the other. Step by step through routines and flirting, the cold and suspicious Huo Wujiu is gradually moved by her, who is both money-grubbing and vibrant. The two seek survival comically, with a two-way tug-of-war intertwined with sweetness and punchy satisfaction.
