The heroine Shen Zhiwei is the youngest criminal psychological profiling expert in the provincial department, but she suffers from face recognition disorder (face blindness).
She cannot recognize her parents, her colleagues, or herself in the mirror. She can only "recognize" a person by their voice, gait, smell, and behavioral habits - she lives each person as a file.
She has been pursuing the unsolved case of her mother's disappearance for thirteen years, and she re-rolls half of an old photo clutched in the hands of a corpse.
On the back of the photo, my mother's name is written.
The male protagonist Cheng Jiming, the leader of the special case team and a lone wolf-like elite, is secretly reviewing an old case involving the death of his father.
Two unsolved cases met in the same old filing cabinet.
What he was investigating and what she was investigating were cases done by the same hands.
Intention: Love is not about saving, it is about standing side by side.
