Lin Wan is a well-known illustrator, but due to changes in his childhood family, he is used to disguise himself as "indifferent" and hides behind the drawing board in the rental house to escape from social life; Gu Zhao is a top architectural designer in the industry. He seems to be bright, but he is shadowed by the project accident many years ago, and he is always tortured by guilt late at night. By chance, Lin Wan drew promotional illustrations for Gu Zhao's new real estate, and the two met because of their "extreme pursuit of details" - she could draw his tenderness hidden in the design from the lines, and he could understand her loneliness under the colors. From the struggles at work to the trials in life, Lin Wan gradually let down her guard, and Gu Zhao also walked away from self-blame with her company. When the "sequelae" of the past struck again, they no longer suffered it alone, but held each other's hands tightly, embracing the sun like the evening breeze, and gained an evenly matched love in the healing process.
