In the suspended city "Azure", memory is not only the past, but also a commodity that can be extracted, edited, and traded. Ling Chen, a skilled independent "memory master", can heal the scars of memory and reproduce the most beautiful moments. He originally wanted to stay away from the world in his own world and protect this fragile art.
However, a dangerous commission from a mysterious woman dragged him into a whirlpool from which he could not turn back. A broken memory, like a key, opens the dark door to the heart of the city. The master of memory, the pursuing phantom, the "Cradle" project hidden under the aura of technology... Every fragment of memory that is repaired pushes Ling Chen deeper into the abyss.
When false happiness is about to cover the whole city and replace real life with the prison of thought, Ling Chen must make a choice: Should he continue to be a bystander who restores beauty, or become a fugitive who delivers the cruel truth? In this war about memory and forgetfulness, reality and fiction, his only weapon is the hands that can penetrate into the depths of the soul.
