"Sister, your reason is the collection I most want to tear into pieces."
Leng Yuening is the chief medical examiner of the Municipal Bureau and a believer in order where rationality is paramount.
Su Nian is a new sweet-type intern profiler and a member of the secret organization "Observers", who regards guiding and observing the "rational collapse" of others as the supreme art.
A serial murder case tightly tied the fate of two people.
Each deceased person is engraved with a letter - C, Y, N, L...
When the mark pieced together to form Leng Yuening's name, and when Su Nian held her scalpel and asked with a sweet smile, "Who's next?", Leng Yuening knew that she had met the most dangerous prey in her life.
Also a hunter.
Su Nian carefully planned and guided her to track down the "Collector", admired her calm analysis, and looked forward to the moment when she collapsed.
"Look at me, sister." Su Nian whispered in her ear, her voice bewitching and crazy, "Only I can make you fall from the altar of perfection and be dyed in my color."
And Leng Yuening restrained her beside the autopsy table with her backhand, the blade of the knife was close to her neck, and her voice was cold:
"Okay. Let's see if you drive me crazy first, or if I bring you to justice first."
As everyone knows, they are the only "treasures" in each other's eyes that must be kept privately.
When the truth is revealed, their relationship has completely lost control in the dangerous temptation...
