Ying Ying's world is only black and white. She was born unable to perceive colors, and her life was like a faded old movie, until her childhood sweetheart Tan Mingze reappeared. He is a talented painter with brilliant colors, but he cannot paint the world in her eyes.
An accident ten years ago separated the two. Now that they are reunited, Tan Mingze is determined to "find her color" for her. But as the investigation deepened, they discovered that Ying Ying's color blindness was not born, but was related to the mysterious death of Tan Mingze's father. The basement of the abandoned hospital, the dark blue graffiti, the deliberately erased memories... All clues point to a secret organization called "Qingyang Hui".
When Ying Ying's dreams begin to appear dark blue, and when Tan Mingze's paintings distort uncontrollably, they must face the shadow of their childhood. The truth is cruel and gentle - the only dark green she can see is the last protection that Tan Mingze's father left to her with his life.
"If my world is destined to be colorless, then you are the only exception."
