In the future city "New Gal City" where neon lights are flashing and floods of data are sweeping across it, the advancement of science and technology has solved almost all human physiological problems, but it has made emotions increasingly alienated and even regarded as an elusive "flaw". Memory restorer Yan Jichen, with his calm and precise data analysis skills, has helped countless people reshape or delete broken emotional memories, but this has also locked his own heart into a cold digital fortress. However, when the mysterious and cold client Ning Youyue stepped into his consulting room with a highly tampered and contradictory memory, Yan Jichen's peaceful and routine life was completely broken. On the journey to trace the truth of Ning Youyue's memories, he not only found that he had touched upon a huge conspiracy hidden in the digital abyss to manipulate human emotions and identity, but he also began to face the deliberately forgotten "emotions" deep in his heart - as well as the past that was entangled with Ning Youyue and blurred like a phantom. This is a cyber journey about truth, redemption and emotional return. The reconstruction of each memory may reveal shocking "heart traces".
