Gu Chi returns to the first day of school at age 18. Faced with a request from his high school classmate Su Man, he chooses for the first time not to accommodate her. Instead, he uses the educational entrepreneurship funds given to him by his father to purchase ten old apartments in the Dongji Factory Family Compound. While others see nothing but rundown old apartments, he sees publicly available development plans, rental income projections, and contractual risks. He refuses to touch properties with unclear ownership, rely on luck, or mistake sound judgment for a shortcut. Through renovation, renting, and property management, he teams up with Liang Ning, a law student, to negotiate prices, inspect properties, and document every contractual detail, gradually turning the ten apartments into a professional property management service.
