The experimental subject Yun Yun has the ability to change his appearance when touching people. In order to escape from the inhuman laboratory, he disguised his identity for a long time and wandered on the run. The organization sent Farewell who had the same appearance as him to pursue him, and Farewell originally created and sacrificed his life to save the person he met. There was a confrontation in a high-rise building, parting pushed the meeting down, and the two people's memories completely merged when they were dying. The two mirror images of old enemies, after sharing their past and pain, became sincere to each other in the endless entanglement.
Intention: Meeting is an accidental encounter, parting is ultimately an entanglement. Two mirror souls controlled by fate, in opposition and symbiosis, break away from the fate of chess pieces, and fight against endless loneliness with love.
