A rain in the used book market caused Qiao Luo, who was focusing on sketching, and Bian Zhiheng, who was in a hurry to take shelter, to smash the paint can. When the indigo bloomed on the yellowed pages, they all thought it was just a damp episode. Until three months later, Qiaoluo discovered a bookstore that was being renovated in the old neighborhood where he often visited. The owner was actually the man who talked about "compensation." When Bian Zhiheng asked her "what should it be called" with a blank signboard, Qiao Luo looked at the wet mortar on the wall - darker than pure white and lighter than carbon black, and suddenly said: "Let's call it the seventh shade of gray." This bookstore became their boundary. She spent the whole day in the corner by the window with her painting tools, and he used a calculator behind the bar to type out life. The two completely different textures of life gradually smudged out with gentle transitional colors in the sound of the pages turning.
Concept: Two completely different people will collide with each other.
