The hospital intensive care unit is the closest place to death. What stands out between life and death is not only the value of life, but also the ugliness of death. It is too superficial to understand the passing of a life in this way. Life always tells you its own flaws in one way or another, and you must discover the beauty of life at the same time. Such a unique perspective is a characteristic that distinguishes a doctor from ordinary people, especially for doctors in the intensive care unit who are closest to death. The novel tells the story of life and death through the perspective of a young doctor in the intensive care unit, and the human nature behind life and death.
