The two male protagonists, the cold and taciturn ancient book restorer Shen Yan (who is distant on the surface, but in fact is extremely obsessed with the stories behind the antiquities) × Lu Shi, the live broadcast blogger of cultural relics who escapes from the lively world (talks in front of the camera, privately knows little about "old things" but is full of awe), have an intersection because of a damaged silk painting from the Song Dynasty. In the process of restoring cultural relics, they gradually repair the "cracks" in each other's hearts.
