There is a Maoyan Bookstore in the world, which collects not books, but obsessions. The shop owner Chang Xi washes away every "bad soul" like moonlight. And every mistake committed by obsession must be redeemed by the person with the obsession. She believes that obsession is an unfinished story, and her duty is to write a gentle final chapter for each story, but she herself forgot the origin until one day...
Concept: The moonlight-like shopkeeper Chang Xi is engaged in a special job in the mysterious Maoyan Bookstore: cleansing souls stained by obsession. But she does not eliminate regrets, but guides the lost to reconcile with the past, tempering the "turbid soul" of life into a glimmer of light that illuminates the way forward. Chang Xi's appearance remains eternal, but she cannot remember her origins.
