This is an anti-conventional urban healing novel that tells an absurd yet heartwarming story between a hard-core cleaning lady and an insomniac billionaire CEO. [Introduction] Shanshan, 50 years old, divorced and sterilized, is the cleaning supervisor of the top apartment "Cloud". Her only goal in life is to save enough money to pay for social security and wait for retirement in peace. 28-Year-old Huo Yanchen, as the president of the Huo Group with a net worth of hundreds of billions, is extremely powerful but has suffered from severe insomnia for five years. He can only survive by relying on powerful sleeping pills. An unexpected "door lock repair" task caused Shanshan to break into the forbidden area of the No. 1 Presidential suite. On the night when the drug was out of control, Huo Yanchen was shocked to realize that only by being next to this 50-year-old woman who smelled of cheap soap and disinfectant could he get a long-lost night's sleep. Faced with a "sleep consultant" contract with a monthly salary of 200,000 yuan, Shanshan, who was sober in the world, threw out the sterilization certificate and disclaimer. She insisted on not resigning because she "cannot cut off social security" and offered a nursing worker a salary of 300 yuan a day. As a result, the style of painting began to become outrageous: the billionaire president confiscated the bus pass just to pick him up in person. Not only did he learn to twist Windsor knots with his hands, but he also ate noodles cooked by Shanshan with a pile of rotten tomatoes worth one yuan. During this trial period called "Human Sleeping Pill", Huo Yanchen found his only salvation and support in Shanshan, who used fifty years of life experience to quietly handle this arrogant business emperor while picking up legal "second-hand wool". This is a healing journey of human sobriety versus extreme paranoia.
