Song Jin is an antique appraiser who opened a small shop in the old city to "make the final decision". Others think she has a poisonous eye, but in fact she relies on another ability - she can "smell" the remaining emotions on objects. Fear is the smell of rust, sadness is the smell of moisture, and deception is the smell of sourness. She never said anything, she just used it secretly.
One day, a strange man left a bronze mirror. When Song Jin touched it, the strong smell of rust rushed up - that was extreme fear. Then she discovered that antiques from different origins and different eras had the same person's fearful signature attached to them. She followed the clues: a dead second-hand dealer, a deserted second-hand store, an antique dealer with a sour smile, and the code in the middle of the scroll.
What made her most uneasy was the lacquer box. Things from the late Ming Dynasty were so well preserved that they seemed too good to be true. As soon as I touched it, the smell of three hundred years of dust hit my face. This thing shouldn't exist.
When antiques are no longer just antiques, when the remaining emotions on the objects point to a secret that has lasted for three hundred years, Song Jin discovers that her own past has also been involved - her parents' car accident was not an accident.
