Yu Man's profession is a "family risk manager" - in popular terms, he works as a "scavenger" for top wealthy families, dealing with issues left over from history that have never been seen. The top wealthy Huo family she serves is the climax of her career and the final chapter of her career. When she joined the company, the old man of the Huo family signed a retirement and pension agreement with her, promising that as long as she sorted out and kept the Huo family's account book that recorded the dark history of three generations of people, she would be able to get a pension that she could not spend all her life. Yu Man worked diligently for five years and was about to wait until the old man left Hexi to take money and retire. As a result, before the old man died, he couldn't take a breath and forgot to tell his "one among the best" children - none of them could move! Ever since: The eldest son, who wanted to clean up the family business and run for parliament, came to her door with a check and a killer: "Ms. Yu, smart people know how to choose." The second daughter, who was in charge of the family entertainment empire and had a chaotic private life, handed her a forged psychiatric evaluation: "Give me the ledger, or you can go to a mental hospital for retirement." The youngest son, an illegitimate son who looked harmless but was actually ambitious, sneaked into her apartment late at night: "Sister, let's work together and kill them. The Huo family will be ours." Yu Man: ...(Smile) I'm just a migrant worker who wants to retire safely, don't force me. Later, the children of the Huo family discovered that this seemingly unarmed archivist not only had a clear grasp of their dirty data, but also had all the evidence that made them completely defeated. Yu Man has coffee in one hand and a tablet in the other.
