Lingshan is the most difficult fabric designer in the camping circle. She can make a piece of cloth shine as softly as moonlight under the scorching midday sun, and she can also drive people crazy with a coating difference of 0.01 Mm. Qi Shen, her ex-boyfriend of five years after breaking up in college, suddenly became her client - the R&D director of a competing outdoor brand. He came to her for technical evaluation with a canopy that was billed as "full blackout and zero transmission". She revealed the fatal flaw in the product within three days: the coating thickness deviation exceeded 0.03Mm, and light leaked like a sea of stars after aging. Thirty thousand mass-produced goods were facing a recall, and Qi Shen fell into her laboratory from the cloud. But she didn't know that he dropped out of school without saying goodbye because of depression and bankruptcy, and she didn't know that his original intention of entering the industry was the sentence she wrote in her graduation project: "I hope my design can protect everyone outdoors." When the lie of full shading was penetrated by the tenderness of diffuse reflection, and when the five years of hatred were melted away by the 0.01Mm buffer layer, they learned one thing again under the canopy - the best shading is not to kill all the light, but to let the remaining light be just enough to see each other clearly.
