Su Tiezhu, a modern female nanny, accidentally slipped into a book about the abuse of an ancient boss and became a vicious female supporting character with a tragic end. Faced with the difficulties of the mean elders, the harassment of the bully male partner, and the stupid thieves who appeared from time to time to cause trouble, Su Tiezhu, a woman with a bold nature, decided not to do it and directly fought back with fists. With her brute strength and straightforward personality, she not only successfully reversed the fatal ending of the female protagonist in the original book, but also unexpectedly cured the male protagonist, a high-school CEO who was cold on the surface but actually suffered from emotional and cognitive impairment. In the process of defeating scumbag men and fighting against the best to save herself, Su Tiezhu's unique personal charm attracted the hidden bosses in the original book, and eventually she changed from the top female supporting role that everyone shouted at to the bosses' apple.
