[4] Because of a car accident, the high-IQ and low-EQ girl Cha Xiaodao accidentally met the villain Mo Feili who was a full-time debt collector.

Thinking back to the time when she broke off relations with her mother and was fired by her boss, she became even more desperate.

By chance, Cha Xiaodao saw an advertisement for the doctor who specialized in treating difficult and complicated psychological diseases.

The doctor also told Cha Xiaodao that Mo Feili was also a "medicine" that could cure her psychological problems.
