"Can I have a good end by choosing death?" Jiang Zhijin, an ordinary researcher from Earth, has been taking care of his sick father for many years. His father longs to die due to the pain of illness, but his application for euthanasia is rejected. Jiang Zhijin, who was unwilling to help his father with euthanasia, was struggling internally, but he had to continue to help his father fulfill his wish of "choosing death." While Jiang Zhijin was looking for a way to fulfill his father's wish, he came to the Hengxu world by accident. Here he learned that people are born with the right and mechanism to "choose death", and that "blindness" is the organ that controls death. Jiang Zhijin meets Jin Hao from the Hengxu Death Mediation Bureau and agrees to help solve five cases related to "blindness" in exchange for the opportunity to bring the "pseudo-blind" back to the original world. He tried to help the teenager get out of the brink of suicide for the first time, but the result made Jin Hao dissatisfied. In the second case, a debt-ridden office worker died of extreme fear, and Jiang Zhijin and Jin Hao finally worked together to find a way to save him. The third case is about an old man who is suffering from illness in his later years. Jiang Zhijin hopes that he will have good memories of his life, but the old man still chooses to disappear... Jiang Zhijin is confused about the "choice of death" in Hengxu's world. It seems to be an active choice, but in fact it is a forced choice. So, does this meet people's expectations of "dignified and good death"? Can Jiang Zhijin finally get his own answer and fulfill his father's wish?
