Su Wan, a girl from an ancient book shop in Lin'an, was born with the ability to discern the whispers in the paper and gain a glimpse of the past of ancient books. While repairing a broken scroll, she accidentally awakened the sleeping spirit of the book, and unexpectedly involved Shen Yanzhi, the "scroll keeper" who guarded the ancient book. When the secrets between the pages of the book are gradually revealed, the ancient books are stolen and the book spirits react one after another. The two are forced to join hands to explore the thousand-year secrets behind the ancient books in the fragrance and mist. They also unlock each other's buried destiny in the protection and redemption.
