After living together for a year, Jiang Wanning has been buying groceries and cooking every day after work, while her roommates contribute only 500 yuan a month toward food expenses. When new roommate Du Xiaoman moves in, she claims that her boyfriend will cook for everyone for free and persuades the others to stop eating Jiang Wanning's meals. But the supposedly free dinners soon come with demands for Jiang Wanning to wash vegetables and cut meat. Seeing through her roommates' moral manipulation and scheming, Jiang Wanning decisively walks away. She then lands a corporate group catering order and uses her cooking skills to start a new chapter.
