Psychologist Lin Changmo has never encountered such a patient.
The talented female writer Yi An walked into the clinic calmly and analyzed her "condition" like discussing the weather. She was rational and alienated, and all indicators were improving.
It wasn't until the news of her suicide came that Lin Changmo discovered those small and desperate secret words on the edge of the medical records: "Save me... But I'm not worth it."
The huge guilt pushed him to the brink of danger - with the help of forbidden technology, he broke into her dead world of consciousness and returned to the small northeastern city fifteen years ago.
This time, he is no longer a doctor, just a silent neighbor brother. He had to watch everything she cherished being crushed by fate one by one, and accompany her through the long and painful fifteen years, looking for the "lesion" that led to the final outcome.
But can he really just watch? When the warm daily life is destined to collapse, is this companionship across life and death redemption, or another more cruel execution?
