Shang Mian, who was chasing the prisoner in the fish market, was smelly and accidentally bumped into the car of Yu Yunchu, a severe mysophobic. On the premise that good citizens strictly abide by traffic rules, Yu Yunchu successfully lost the prisoner and left Shang Mian in the suburbs and drove away. One case after another, the male and female protagonists began to understand each other. It turns out that although Yu Yunchu is a plastic surgeon, he only performs reconstructive plastic surgery. His "Clear Sky Project" has helped countless patients with congenital deformities and accidental disfigurements. He seems to be vicious and hypocritical, but he is actually kind-hearted. Although Shang Mian has a bad temper and is careless, there is actually a scar in her heart that she has never been able to touch. Her deceased boyfriend is her unchanging original intention and belief, and Yu Yunchu has gradually walked into the door that has been sealed in her heart for a long time. After the ups and downs, the dust settled, and Shang Mian finally found the real culprit who killed her boyfriend. With Yu Yunchu's company, Shang Mian also got out of the shadow in her heart, and continued to perform her duties as a people's police, guarding the lights of thousands of homes, but this time, there was no one around her anymore.
