Who in the family understands? Unemployed social worker Lin Dachun is bound to a crazy life-sustaining system - just create a "pupil earthquake" to redeem rewards! From then on, he relied on madness to fight against PUAs in the workplace, outsmart his strange neighbors, and rectify the internal chaos. From being forced to open a business to taking the initiative, he used absurdity to fight reality, used madness to cure anxiety, and finally led the people to usher in a new era of "rational madness"! Whoever falls in love with whomever in this class falls in love, I will go crazy anyway!
