Chen Mu, an ordinary migrant worker, has another identity - a food blogger who makes secret visits to stores and earns millions a year. The detective's wife Song Zhiyi has always been disgusted with his secret visits to expose businesses, so he only dared to sneak into stores late at night and hide his love in the barbecue and fireworks room. A surprise interrogation exposed all his disguises, and the two people in the interrogation room revealed all their knots. Song Zhiyi saw through his concealment and understood his original intention of exposing the shady shop; Chen Mu shed his playful appearance and saw his wife's hard work and vulnerability in handling the case. In the past, estranged couples reconciled, worked together to track down unscrupulous businesses, confessed to hiding diamond rings on skewers, and waited for childbirth together at home. The quarrels and tenderness of ordinary couples were all integrated into the three meals and fireworks.
