In the shared apartment, Gu Anran is responsible for her roommates' dinners, collecting four hundred for food expenses per month, and often subsidizing ingredients out of her own pocket, only to be slandered by her roommates for taking kickbacks. New roommate Meng Yao feigns cooking for free to win over everyone, condones her boyfriend freeloading, and subsequently raises prices to extort money, using spoiled zombie meat and inferior black oil for cooking, triggering a mass food poisoning. Roommates who once trampled on kindness are full of regret, but to no avail. Gu Anran strikes back with evidence in hand, starting a business and establishing a career through her culinary skills, ushering in a brand-new life.
