Character 1 (Cheng Xiaoshi) sitting completely inside a supermarket shopping cart, casually curled up among groceries, knees bent up comfortably, legs loosely folded and slightly tangled among snacks, bread, boxed food, and canned drinks; relaxed mischievous posture, looking comfortable. He has short black hair reaching the nape, partly tied into a small ponytail, slightly messy, orange eyes with a sparkling gaze, wearing a blue letterman jacket over a white t-shirt, black trousers, gray shoes, white socks, and a black bracelet on his right hand; he is casually holding a snack package and turning his head toward character 2. Character 2 (Lu Guang) standing behind the shopping cart and pushing it, with short white hair, slightly messy bangs, steel-gray eyes with a calm gaze, wearing a white shirt over a black t-shirt, black trousers, black socks, white shoes, and a digital watch on his right wrist; one hand grips the handle while the other holds a small grocery item toward Cheng Xiaoshi, as though asking if they should buy it.
