Introduction to the work: My name is Lin Yifei, 30 years old, a daily porter, a former underground band bassist, and an active single father. She shares a three-bedroom apartment with parkour coach Li Haoran and takes her four-year-old daughter Tangtang with her. I get up at four o'clock in the morning every day to grab the daily statement, and pay for milk powder and rent. Bad luck? No, I have a secret: I get a little lucky once a day, as precise as setting an alarm clock - grabbing the last can of discounted milk powder, picking up 20 yuan, and just escaping the heavy rain due to the temporary work. Then bad luck hit the door on time: there was a hole in the bottom of the milk powder can, the twenty yuan was counterfeit money, and I escaped the heavy rain but lost my mobile phone. There are nine iron rules in the co-tenancy agreement: No noise is allowed after ten o'clock in the evening, otherwise you will be fined for washing dishes for a week; if you don't return tools after using them, you will be fined for running errands and buying midnight snacks. The week when Li Haoran broke his leg in parkour, I was forced to carry him up and down the stairs. I was lucky enough to be a scalper who got a registration in orthopedics - and then I found out that I had registered in the wrong department. I was deducted from my wages by the foreman when I was moving bricks at the construction site, so I tolerated it. Party A temporarily bargained for the shopping mall performance, so I couldn't bear it. Until my daughter was criticized by the teacher in the kindergarten, saying that a child without a mother is uneducated, Tangtang responded with a milky voice: "My mother went on a business trip to Mars, do you have any opinions?" I took out the bass and improvised an arrangement of "Little Star" at the kindergarten parent-child talent show. The bass slap made all the parents mute. The director of the park chased me out to sign a long-term cooperation, and my former band brothers invited me to participate in an underground music competition with a prize of 50,000 yuan. But a little luck tells me: the more beautiful, the worse the fall. In this competition, my opponent was the lead singer who kicked me out of the band.
