Su Guiyuan, a psychologist who is burdened with heavy guilt for his mistakes, lives alone in seclusion on the edge of the old city, confronting himself all day long. His soul was like an abandoned palace, echoing with unresolved regrets and questions. One day, a strange boy broke into his world and brought a riddle about the "River of Forgotten" - it is said that only those who truly understand the pain of others can cross the river and atone for their sins. Su Guiyuan is forced to embark on an unconventional road to redemption: he must travel through the maze of other people's hearts, explore the nature of pain, talk to everyone abandoned by time, and awaken the dormant resonance. Every spiritual confrontation is a self-justification of the soul. He gradually discovered that redemption is not about self-forgiveness, but about accepting the cracks in life and the pain of others with a calm heart. The novel uses timeless writing to carve out the shadows and glimmers deep in the soul, exploring the deepest temperature of human nature between loneliness and hope.
