Top perfumer Lin Shuang was betrayed by her friend Zhou Yu'an, so she hid her identity and became a cleaner at Star Entertainment Media Company, but met Sunshine Music Producer Shen Yao. Shen Yao was attracted by Lin Shuang's cold temperament and took the initiative to approach her, gradually opening her frozen heart; while Zhou Yu'an became jealous of Lin Shuang's talent and designed to destroy the relationship between the two and expose Lin Shuang's past trauma. Accompanied by Shen Yao, Lin Shuang stepped out of the disguise of "cleaner" and faced the past. She used perfume-making techniques to counter Zhou Yu'an's conspiracy, and finally overcome the obstacles of sadomasochism with Shen Yao and achieved a healing ending.
