This is a romantic story that spans time and space, ingeniously interweaving the restoration of cultural relics with modern love. Lin Zhiwan, who majored in archeology, worked as an ancient book restorer in the city library, and unexpectedly met Mo Yu, a top ancient book collector who was reserved and calm, because of a broken ancestral inkstone. Their names have the same pronunciation, but their fates overlap quietly due to a dusty friendship between their ancestors. From the century-old fingerprints on the fragment of "Hai Cuo Map" to the pair of "Inkstones" restored on a rainy night, to the family past hidden in the plant atlas of the Republic of China, in the process of exploring the stories behind the cultural relics, they gradually uncovered the unfinished regrets of the previous generation, and also found their own emotional bonds in the fragrance of ink and fragments of time. The story integrates professional elements such as cultural relic restoration and ancient book textual research, and uses the unique perspective of "cultural relics as a medium and time as a guide" to tell the story of how two souls can transcend the fog of time and space and see their true selves in each other's eyes while protecting cultural heritage. There are both the ingenious details of the restoration of cultural relics and the warm throbbing of two-way redemption, which is clearly different from traditional romance routines.
