In 1995, a young man from the future began to write letters to the Central Committee.
He predicted Japanese politics, border friction, and floods, and all three things came true.
The state secretly set up a special task force with a deadline of one month to find the letter writer.
I don't know who the author of the letter is, I only know that the other person said something——
"Please believe that I am on your side."
As the task force approaches the truth step by step, the person hiding in the dark seems to be waiting to be found.
