He is the most precious "Fragrance Master" of the Yan family. He is extremely talented and can create the most beautiful fragrance in the world, but he is also the most vulnerable prisoner - he has been sick since childhood and coughs up blood regularly. He is kept within a high wall by the family just to squeeze out his talent.
He is Cheng Yi, a taciturn medical apprentice. The silver needle in his hand can save people, but it cannot save the young man who is trapped between spices and illness. Until they met on a snowy night, he handed over a honey candy and the only promise in his life: "As long as you blow the silver whistle, I will come."
However, when the greed of the Yan family presses harder and harder, and when the value of "Fragrant Master" is squeezed to the end of his life, Yan Cheng finally understands that no matter how beautiful the fragrance is, it is poison after all. And Cheng Yi must lead him to escape from this gorgeous imprisonment before he coughs up the last drop of blood...
"If perfume is a shackles, then freedom is the only fragrance in this life."
——This is a story about the mutual redemption of a sick genius and a guardian, about fragrance and blood, cage and freedom, and the oath never to be broken in the silver whistle.
Purpose: The meaning of life does not lie in talent, but in how to live, love and fight in your own way.
