The Su family, once a legend in the world of perfumery, fell into decline with the loss of a unique perfume called "Floating Day". As the only descendant of the Su family, Su Wankong has an extraordinary talent for smell, but he can only work as a low-level researcher in a spice company, silently guarding the family's last secrets.
A sudden acquisition made her meet the ruthless business emperor-Lu Chenzhou. Like a precise cheetah, he sensed the huge value hidden in her. He used the replica of "One Day" as bait to drag her into his huge and cold perfume empire "Aura".
This is a transaction with fragrance as the bet, and also a game with sincerity as the bargaining chip. He taught her the rules of survival in the business world, but she used fragrance to awaken his dusty memories and emotions. When the secrets of "One Day" are revealed layer by layer, it involves not only the grudges between two generations, but also a cruel truth that can destroy everything. Love and hate, trust and betrayal, intertwined and collided in the fragrant aroma. When all the glitz and glamor dissipated, they discovered that each other was the only breath in each other's lives that could not be erased or replaced.
