In an apocalyptic world where emotions are deprived of in exchange for survival, memories can be traded, and human hearts are like commodities.
Under the shelter of the dome, the city is divided into a radiant upper level and a dark and despairing lower level. Lu Zhou, a former genius emotional tuner, was forced to accept a fatal commission that went deep into the restricted area in order to save his sister whose emotions were being swallowed by "dust". What he is looking for is not a cold creation, but a living miracle - a mysterious girl, Fei, who is not bound by the laws of doomsday.
Her existence is the key to saving the world, and also the source of death.
When the giant corporation that controls everything forces them into a desperate situation, and when his former best friend turns into the coldest hunter, Lu Zhou must make a choice: Should he sacrifice the girl in order to survive, or should he burn his last remaining warmth to protect the pure humanity that has long been forgotten by the world?
At the junction of light and shadow, a gamble concerning the survival of human souls has quietly begun.
