In the "Light Picking Office" deep in the old alley, memory repairman Wen Gu uses his calm professionalism as a shield to sneak into other people's memories and heal their wounds. It wasn't until best-selling author Shen Xubai came to her door with a manuscript full of alterations and entrusted her to find her depleted inspiration that her rules were broken for the first time.
The consciousness sinks into Shen Xubai's memory, but the review repeatedly falls into the fictional world written by him - the bookstore of the Republic of China, the island town, and the martial arts world. She plays different roles, and Shen Xubai always shows an inexplicable familiarity and tenderness to her in every world.
As memories travel, the secrets of the cherry blossoms in the old childhood alley and the same conch gradually emerge, and the long-lost past of the two and Shen Xubai's deeply buried guilt trauma are revealed. In the end, Wen Gu healed him as an "old friend", and the only heroine in Shen Xubai's new book finally looked like Wen Gu.
