Su Lan shares a rental for a year, buying groceries after work and cooking for her roommates, charging only 500 for groceries each month. New roommate Meng Wei claims her chef boyfriend provides free meals, and the roommates eat the food Su Lan cooks while demanding refunds and accusing her of making a profit on the price difference. Su Lan refunds them, stops cooking, and moves out. After handing over her work, she opens a stall selling 22 homestyle meals. Meng Wei steals her old dish photos and name to sell 18 combo meals, harming her orders. Su Lan forces the other party to correct the refund in the original group chat and refuses to let her old roommates use emotional ties to kidnap and reconcile. In the end, she would rather turn down extra-paid orders than protect her rest and movie date with a friend.
