In order to raise money for her son's surgery, the protagonist Su Wan unexpectedly becomes the "nanny" of Fu Jingshen, her previous one-night stand and the biological father of her child. She tries her best in the back house of a wealthy family, using top-notch public relations techniques and psychological tactics to solve low-level workplace bullying and stabilize her position.
** Su Wan's son Su Xiaoxing was diagnosed with congenital heart disease and urgently needed 500,000 yuan for surgery. Su Wan spent all her savings but still had little money to make, and accidentally saw an advertisement for the Fu family's recruitment of a "high-priced childcare teacher" with a monthly salary of 100,000. Forced by money, she applied for the job. During the interview, Fu Jingshen was impatient with all the applicants due to misogyny and face blindness. Only his "autistic" son Fu Xingran (Su Xiaoxing) took the initiative to grab Su Wan's clothes. Su Wan unexpectedly obtained the position by virtue of his son's "hand-picked appointment".
