Forensic pathologist Song Ci never imagined that his scalpel would cut open more than a corpse. It would also expose the secret he had buried for eight years.
A string of murders rocks the city. Each victim has been precisely dissected, the wounds as meticulous as diagrams in a textbook. The killer wants neither money nor sex. Instead, they leave one “medical lesson” after another at each crime scene, and Song Ci is the only one receiving them. Messages arrive from an unknown number, addressing him as “Teacher” and inviting him to grade their “homework.”
Following the trail of blood, Song Ci discovers that the killer’s logic is exactly like his own at seventeen: using the coldest blade to punish those the law has let slip through the cracks.
At the dissection table, he must face an impossible question: between hunter and prey, which one is the reflection in the mirror?
The blade falls. The answer has long been etched into his bones and blood.
