The female protagonist has an ordinary identity on the surface, maybe a college student or an office worker. Hiding a secret requires something special, such as being able to see ghosts, predict the future, or have special abilities. The settings of friends or enemies should be reversed, for example, the seemingly good guy actually has a problem, or the seemingly bad guy actually helps. The protagonist, Lin Qiubai, is a 24-year-old medical school dropout who works night shifts in a funeral home to take care of his sick father. Eerie details that defy common sense: bodies move while she's on duty, or ghosts caught on camera. The empathic dilemma: Father's medical bills and debt stress. Mysterious item: The old camera left by my father can capture ghosts. The story begins when Lin Qiubai works the night shift at a funeral home and discovers an abnormality in the body. At the same time, she meets a mysterious man who seems suspicious but may actually help her. Each chapter leaves you with suspense, like solving a small problem, but a bigger mystery emerges, like a body disappearing and a camera showing clues.
