The Memory Garden.

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.
