Su Wanye is an independent perfumer who sticks to her dream in a corner of the city. Her world is pure and fragrant. Fu Chengyan, a man who stands at the top of a business empire, lives a luxurious but lifeless world - he suffers from a secret "acquired anosmia" and cannot smell any synthetic aroma. A niche perfume salon made Su Wanye's original work "Wan Lai Silence" the only one that could break into Fu Chengyan's sensory world. Like a wild beast chasing a lonely light, he used an overbearing contract that he could not refuse to imprison her in the golden cage he spent a huge amount of money to build, and only made fragrance for her. He was cold, paranoid and controlling, and regarded her talents as private property. She is proud, tenacious and yearns for freedom, struggling painfully under his imprisonment. When she unexpectedly discovers his hidden secret, the fragility and desire behind that cold contract, everything begins to change quietly. How will this entanglement that started with plunder eventually lead to redemption and deep love in the unique fragrance?
