Retired detective Chen Mo received an anonymous package on the thirty-seventh day after his daughter disappeared. Inside was a diary with a blue cover, with her daughter's name and date written on the title page - a week after she disappeared.
"Today Dad went to the river again. He thought I didn't know, but I heard him going out at three in the morning. He always stopped at the same place, staring at the water in a daze. If he knew that I was there too, just ten meters behind him in the bushes..."
Chen Mo's fingers were trembling. This is impossible. The forensic report showed that the daughter had died on the day she disappeared. But the details in the diary—his habit of going to the river in the early hours of the morning, his quirks known only to his family—were all accurate.
As the investigation deepened, more contradictions surfaced: surveillance video showed that the place where the daughter was last seen did not match the description in the diary; a key witness suddenly recanted his confession; the medical examiner changed his story and said the time of death may be wrong. Chen Mo began to hear his daughter's voice at home, see her figure in the mirror, and even smell her usual shampoo fragrance.
When the police dug up another body by the river, Chen Mo found that the last page of the diary read: "Dad, you finally found me. But are you really sure that's me?"
In this small town where it always rains coldly, the truth is like the reflection on the river, within reach but never truly graspable. When the last piece of the puzzle falls into place, Chen Mo must make a choice: believe in the cruel reality, or embrace the beautiful illusion?
