Erased Tomorrow

In this world, everyone's future is recorded in a huge book called "Tomorrow Book". When a person's "tomorrow" is written down, his life moves along the established track. But one day, the protagonist suddenly discovers that his "tomorrow" has been completely erased. What will happen to people without a future? Is it freedom? Is it a curse? Or is the world simply unable to accommodate undocumented "deviants"? He began to hear voices that others could not hear, and saw shadows that had been deleted from history. And a huge truth is approaching: All so-called destiny is written.
