A bizarre experiment on a rainy night, a storm of memories sweeping through reality.
Lin Shen wakes from a coma to find a strange ouroboros-shaped scar on his chest and his mind filled with fragments of memories that do not belong to him: screams from an operating table, the metal door of an underground laboratory, and the twisted face of his younger brother, Lin Yuan. When Dr. Chen's corpse in the morgue suddenly opens its eyes, and the ouroboros's black ribbon seeps from reality into his dreams, he finally realizes this is no nightmare. It is a carefully altered maze of memories.
"When memory becomes a weapon, you can no longer tell who the prey is, because the most terrifying monster has been living in your brain all along."
