Tang Xiaotang, 25 years old, is an ordinary social worker, with a monthly salary of 6,000, and rents a partitioned house in a village in the city. One day she grabbed a luxury apartment on a rental app, and the monthly rent was only 1,000 yuan. When I moved in, I discovered that the landlord was Lu Beichen—the president of the Lu Group who always had a cold face in financial news. What's even weirder is that this billionaire boss knocks on her door on time every day after get off work and asks the same question: "What's for dinner tonight?" Because the last line of the rental contract reads: "The tenant must prepare dinner for the landlord every day and reimburse the cost of food." This absurd contract binds people from two worlds together. When Tang Xiaotang discovered that Lu Beichen only ate one bowl of tomato and egg noodles she made every night, she had a vague feeling that things were not that simple.
