In the dome city "Lumen City", memories are commodities that can be extracted, traded, or even erased. In this way, Yongguang Group builds a perfect world without pain.
Lin Xun is a lonely "soul painter". His job is to color memories and paint chaotic emotions into priceless works of art. He originally wanted to spend the rest of his life behind the canvas, until an anonymous soul crystal allowed him to draw a murder that did not exist.
A painting pushed him to the road of escape. A mysterious woman codenamed "Nightingale" dragged him into the abyss of resistance. The cold "Purge" follows him everywhere, vowing to burn him and the secret together.
In order to survive, and to recover the reality that was taken away, Lin Xun must hold on to the paintbrush, use the hypocrisy of the entire city as the canvas, and use all the forgotten pain as fuel to paint a stroke that can overturn the world.
When the ashes of light fall, he wants everyone to remember that what makes us human is precisely because of those scars that cannot be erased.
