Librarian Shi Tian has lived alone for many years, is lonely and silent, and suffers from obsessive-compulsive disorder.
The world is nonlinear, and time is trapped in countless "three-day cycles."
One day he woke up in an abandoned church, the air was sweet, and he was half-shot in the mirror.
His cell phone showed that he had been here for three days, but he had no memory.
The silver bracelet was branded with "See you in three days", and the outline of a corpse appeared on the altar.
He gradually discovered that he had witnessed his father accidentally killing his mother when he was a child.
And because of his silence, he killed the neighbor girl who revealed the truth, and was dragged into reincarnation by resentment.
The mirror is a channel, and compulsive behavior becomes a memory anchor.
Each cycle gets closer to the truth and tears away the scars in the heart.
The real terror is not the ghosts, but the self that dare not face it.
He must use strategies to break the closed loop of obsession, face his guilt, and break the reincarnation.
