In 2077, when data is immortality and memories can be traded, the ace memory stalker Ling Su is a desperado who only cares about money. He wallows in his past failures until a business comes knocking on his doorstep, dragging him into a more dangerous whirlpool.
Mission target: Code-named "5563", a vegetative man lying in a life-sustaining cabin. Her brain is a maze, hiding secrets that can wipe out the world's hegemon "Original Group".
Sneaking into her memory, Ling Su witnessed the heavy rain flowing against the current, heard the whispers in the library, and encountered guards made of his own fear. He thought he was a hunter, but found that he was already the prey. The woman known as the "Nightingale" used her broken memories to set up a final mystery about redemption and freedom for him.
When the boundaries of memory melt and the order of reality collapses, Ling Su must make a choice: steal secrets in exchange for false relief, or stand side by side with a ghost and sing a song of resistance for the entire world?
He didn't know that the end of this journey into other people's souls was to find himself.
