Ji Beichen is the youngest deputy captain on the criminal investigation squad. He has a perfect solve rate, but also a secret no one knows: another personality, “Ashuo,” lives inside him. Calm and ruthless, Ashuo excels at thinking from a criminal’s perspective. Whenever a case reaches a dead end, Ji Beichen has to “let him out.” But while investigating a string of disappearances, Ji Beichen wakes to find his hands covered in blood and an unfamiliar corpse beside him. All the evidence points to him as the killer. Stranger still, he has no memory of what “Ashuo” did during that time. Did he lose control and kill someone, or has someone framed him? As Ji Beichen searches for the truth, he discovers that the conspiracy behind the case leads straight to the memories from his childhood that were deliberately erased. And the voice that has always spoken to him inside his mind, is it really his other personality?
