Love is redemption, and it is growth when you meet your opponent. We are not anyone's white moonlight or cinnabar mole, but a lighthouse looking side by side.
Su Wan, a 22-year-old genius cultural relic restorer, met Gu Yanshen, a 28-year-old technological upstart, because of a mysterious ancient painting restoration project. An ancient painting with a hidden mystery leads to a half-century-long dispute between the two families. Under the double test of career and emotion, they initially had different goals, but were gradually attracted to each other's profession and soul. Finally, they jointly uncovered the dusty past. In the confrontation between tradition and modernity, they joined hands to protect their common beliefs and completed their own transformation and growth.
