Chunmei Home-style Restaurant has been open for eight years, doing a thriving business yet unable to save any money. The eldest sister-in-law brings people to eat for free, the mother-in-law casually takes dishes, the brother-in-law meddles in procurement, and the husband hides free meals from her. Until her daughter drops out of a competition due to a lack of money, Luo Chunmei finally awakens. She digs out the old account books, and starting today, she won't offer credit, won't give things away for free, and won't take the blame. Relatives turning hostile, spreading rumors, and buying goods on credit under false names come one after another; step by step, she sets rules and settles accounts clearly. This is not being cold-hearted, it is finally understanding that even as a family, accounts must be kept clear.
