When Lin Xiaoxing was 30 years old, she lived the life she hated most - she worked 996 and was PUAed by her boss. Her boyfriend of five years took away her savings and ran away. The house she rented was suddenly repossessed by the landlord. She was struck by lightning while dragging her suitcase in the heavy rain. When she opened her eyes again, she was back to the year she graduated at the age of 22, still clutching the property certificate for a three-story building in the old city left by her grandmother. This time, Lin Xiaoxing vowed to "lay down and counterattack", change the old house into an Internet celebrity B&B as a landlord, and never be a capitalist's leek again. But just halfway through the renovation, she ran into big trouble: a "weird" neighbor suddenly moved next door, Lu Zeyan, who lived in seclusion every day, but always "dropped out of the sky" when she needed him - he could repair water pipes faster than the real estate agent, and he was more skilled than a professional master at clearing sewers. Even if a guest of her B&B lost a pet, he could accurately locate it. As the contact increased, Lin Xiaoxing discovered that this neighbor was not only handsome, but also hid many secrets. Her own "restart of life" did not seem to be a simple accident. The two went from being disgusted with each other to working together, and together they turned an alley in the old city into a place for Internet celebrities to check in, and by the way, they unlocked new possibilities about life, dreams and love. Lin Xiaoxing also changed from a graduate who just wanted to "show off" to a "top landlord" that everyone envied.
