Cha Xiaodao (played by Sun Li) has a very high IQ, but is weak and afraid of things. Mo Feili (played by Deng Chao) is just a gangster, but has an arrogant and domineering personality. A car accident brought the two together. Mo Feili unsurprisingly cheated Cha Xiaodao. With indifferent family affection, frustrated work, and bullied by evil people, Cha Xiaodao was disheartened. He accidentally learned that there was a genius doctor named Zhe Ergen (played by Liang Chao) who specialized in treating various difficult and complicated diseases, so he had the idea of seeking a good prescription from him. What Cha Xiaodao didn't expect was that Mo Feili was also a patient of Zhe Ergen. He was troubled by insomnia for many years and felt miserable. Zhe Ergen told the two that they were actually each other's "good medicine". In order to "cure the disease", Cha Xiaodao and Mo Feili became partners and advanced and retreated together, causing countless troubles and jokes. At the same time, they also formed a deep relationship.
