About this drama
A conservative town's peace is disrupted by an online novel that mirror's a real-life cold case known only to law enforcement. Rookie detective Li Cheng and the mysterious Han Pinmu engage in a high-stakes psychological duel as they navigate a dual-thread narrative where fiction and reality blur. The investigation uncovers buried secrets and explores the thin line between redemption and the inescapable void of the past.
Who this is for
Viewers who like puzzle-box police procedurals where the clues are all on screen and you can try to solve the case alongside the detectives. Skip it if you want romance (there is essentially none), a female-led cast, or a light watch; the subject matter is serial rape and murder.
Our take
Viewers praise the mystery writing for playing fair: clues, including excerpts from the in-story web novel, are planted from episode 1 and pay off without cheating. Ren Jialun's grounded turn as a rookie cop, Qin Junjie's guarded Han Binmu, and the veteran supporting police cast stand out alongside a warm mentor-student bond. The show keeps a dark, early-2010s small-town mood leavened with low-key humour. Common complaints are a slow opening buildup, rushed confessions in the final episodes that leave a few motives thin, and a male-heavy cast with virtually no romance.
Pacing & content notes
Short at 16 episodes and released over five days; most viewers call it tight with no filler, though one reviewer found episodes 1-8 slow groundwork and a couple felt the last three episodes were rushed or flatter than the middle (roughly episodes 6-14 are cited as the most gripping).
Heads up
- Serial murder and sexual assault are central to the case
- A drawn-out on-screen death of a family member
- Loss of a well-liked core character
- Male-dominated cast with almost no romance
