Liu Yuan has always valued family ties very much, voluntarily helping his cousin Liu Qiang and cousin's wife He Liping run a restaurant, attract clients, and deliver group meals for three years. During an ordinary packaging, a ten-yuan packaging box made him see the couple's double standards clearly. Liu Yuan no longer tolerates it, withdrawing human favors, resources, and guarantees, making the restaurant pay the price for cutting corners and petty greed. After experiencing family kidnapping, career trials, and a food safety scandal, he guards his principles and kindness, also understanding that family ties cannot be without boundaries.
