In the future city "Esenberg" where memories can be read, repaired and traded, Lin Zhou, a top "memory restorer", can stitch together the broken memories of others, but cannot piece together the fragments of his own past. One day, a mysterious woman named Anya brings an unexplainable memory: a warm lullaby and a biting cold coexist. In order to solve this paradox, Lin Zhou dived into the depths of Anya's chaotic memory, only to find that the cornerstone of this island of memory was actually his own forgotten past. Between the tampered truth and the cruel reality, he must make a choice, whether to protect a beautiful lie or embrace a devastating truth.
