Jiang Wan lives in a shared house with three other people. Every day after work, she cooks for everyone, while her roommates split the grocery expenses among themselves each month. After a new roommate, Bai Ying, moves in, she claims that her boyfriend can cook for everyone for free, using this as an opportunity to sow suspicion among the roommates and accuse Jiang Wan of pocketing the difference in food expenses. Misunderstood and unfairly accused, Jiang Wan immediately refunds their contributions, stops sharing meals with them, and moves out. Without Jiang Wan taking care of them, the remaining roommates soon encounter one problem after another, from stomach troubles and filthy living conditions to interpersonal conflicts. Only then do they realize how precious the warmth and convenience they once took for granted truly were. Meanwhile, Jiang Wan puts her excellent cooking skills to use by opening a home-style food stall. As her reputation grows, she gradually builds a brighter and more fulfilling new life.
