Fang You-cheng and Li Ching-yi, a young couple in their thirties who long to buy a house of their own, get married, and build a family together, meet Lin Li-chun, a lifelong bachelorette in her sixties who seems icy and distant. They unexpectedly become landlady and tenants. Things do not start well as they struggle to live together, but they gradually learn to understand each other and enter the others’ lives, becoming close house mates with even tighter bond than family.
