Su Xiaoyu, a college student, worked the night shift at a 24-hour convenience store to earn living expenses. She discovered that after three o'clock in the morning, the products in the store would "come alive". Potato chips have become the chatty little fat boy, instant noodles are the gentle big sister, and the ice creams in the refrigerator are competing for the "overlord of the frozen area". Not only does she have to deal with weird products, but she also has to solve the "little supernatural troubles" they bring, and she also has to hide this secret from outsiders.
