Lin Fu, a 32-year-old haute couture designer, was betrayed by his stepsister Lin Wei. He lost the Iris Flower House left by his mother and eventually died of stomach cancer with regret. Once reborn at the age of 22, she was at her father's remarriage party. With her past life memories and awakened "smell memory" ability, she vowed to take back everything and find out the truth about her mother's "accidental car accident". When she joins fragrance critic Shen Yanzhi's "Fragrance Garden", she meets Lu Chen, a perfumer with a poisonous tongue. She and Lu Chen went from tit-for-tat to two-way redemption. This is a revenge that uses fragrance as a blade, and it is also a period of protection that spans time. In the end, she uses olfactory technology to create a business legend, allowing love and truth to linger forever in the years.
