Su Wan, a restorer of cultural relics from the Forbidden City, accidentally traveled across time due to a Southern Song Dynasty jade hairpin engraved with "Jingyuan". In Liuxi Village, Lin'an, where he lived in the third year of Chunxi's reign, he met the owner of the hosta, the jade carver Shen Jingyuan. She brings with her the knowledge of later generations' crafts, and he cherishes the ancient carving skills. The two of them accompany each other day and night, using jade as a matchmaker, and they create a tacit understanding and affection that spans time and space between the blue tiles and white walls. But thousands of years have passed like mountains and seas, and the hosta attracted her here, but eventually sent her back to her hometown. When the modern morning light woke her up, the newly engraved small words on the hosta let her know that this encounter spanning thousands of years was never an old dream with one horn, but the most affectionate remembrance of each other hidden in the years.
