A girl with amnesia woke up in the human world. She remembered only one name, so she called herself Lei Mingyue. Her days in a mountain village were peaceful, until she took in a badly injured man. He called himself Chen Luokui, cold and taciturn, yet always lent her a discreet hand whenever she was at her most vulnerable. She thought he was a fellow sufferer just passing through, unaware that though his heart was full of hatred, he still loved her as always. Echoes of the war between immortals and demons gradually drew near, while fragments of memory returned again and again in her dreams. When wanted posters covered every street and the identity of "Demon Chen Luokui" was mercilessly exposed, she realized she had been searching not only for her lost past, but also for the person who had always stood in the shadows, shielding her from every storm. This is a story about forgetting and remembering. When the whole world curses her name, one person remembers what she looks like when she smiles. Identities can be disguised and memories can be shattered, but through a long search, the heart recognizes the other's warmth time and time again.
