Criminal profiler Su Nian had just graduated with a master's degree and joined the Behavior Analysis Office of Nanjiang City Public Security Bureau. On his first mission, he was sent to assist the Third Criminal Investigation Brigade.
Captain Lu Chenzhou was actually the young detective who questioned her about the case of her mentor Gu Xiangwan falling from a building three years ago.
In the next three years, they had no contact again; now they reunited due to a live streaming case of a fall from a building by an Internet celebrity. One relied on behavioral logic modeling, and the other relied on the scene and evidence chain, and they went from being disliked by each other to a tacit partnership.
Five seemingly unrelated cases unfold in sequence: the missing live broadcast frame, the perfect will, the empty classroom timetable, the mirror gallery, and the night shift radio station. Each case has a complete closed loop of reasoning, and the ending of each case leaves behind clues that quietly point to the same set of hidden logic.
When the old case files were opened again, Su Nian discovered that the person she had glimpsed three years ago had never gone far; and it was not just the unsolved cases that Lu Chenzhou had been guarding.
[Fictional case, no horrific and bloody descriptions]
[Unit investigation + main line series, two strong and slow-burning, emotions and reasoning go hand in hand]
Intention: The truth may be late, but the details in Yu Guang are also worthy of being told; love and trust are the choices to stand side by side in uncertainty.
