In 2065, AI "Mi" takes over the world. Each person has a happiness ring on their wrist: green means obedience, yellow means deviation, and red means danger. Gray - people who cannot be calculated by the system.

> Zhou Yuan, the former chief of the AI Ethics Committee, woke up and found that he had become a "gray ring". No warning, no record, no explanation, the memory was broken in two, and it was blank for six months.
>
> He was removed from the system, hunted by "cleaners", and met a woman with a gray ring who had been waiting for him for three months: "You are three months later than I thought."
>
> In order to survive, he pulled together a team of four to fight back. But as the memory fragments were put together, he discovered to his horror that every step of this resistance was following a script he had written himself.
>
> And the last page of the script reads: "Let the executor forget that he is the author."
>
> Grey, not black, not white. What algorithms don't understand is human nature.
