Hua Xiao Xuan is a witch of a supernatural flower shop called "The Memory Garden," where she helps her customers let go of their fixation and move on with their lives. One day, she meets the man who accidentally stole her sense of smell during her 13th regeneration years ago. The sense makes him immune to her powers and allows him to enter her shop without invitation. She foresees their lives intertwine and the darkness she is fighting against may cause his death someday.

故事開始於一間神秘花店「花之道」。傳說只要是想斷捨離的人，都能在某個時刻，某個街角，看見這間花店的存在。創作理念起源於人們經常因為喜愛鮮花宜人的外觀和香氛而以各種方式種植、購買和佩戴。在生命過程中各種各樣的場合都可以見到花，花是世間言語和情感的借代物，每朵花也都有它的花語，花在本劇中不僅是重要的主軸，更串聯所有人物的情感面。
