Wu Nai, a 62-year-old stingy landlord who owns four apartments and has three million yuan in savings, is diagnosed with terminal cancer and given only 14 days to live. At this critical moment, he activates a life-extension system. By making his three female tenants feel surprised, he can turn back his age by two months and extend his lifespan by another two months. Wu Nai abandons his usual stingy ways, repeatedly astonishing his tenants Bai Xue, Yu Qian, and Sha Lili with rent-free stays and special treatment, continuously extending his life. He buys household appliances and even purchases a house outright, constantly exceeding everyone's expectations. As they spend time together, the three women grow as close to him as family.
