Description：The new works of the popular online horror comic writer Jiang Zhiyun (played by Lee Si-young) have been published one after another and have received rave reviews. However, in her life, she seems to be increasingly unable to distinguish the boundaries between reality and fantasy. Not only does she often encounter extremely realistic horror nightmares, but she also often suffers inexplicable wounds on her body. One night, Xu Meizhen, the editor-in-charge of writer Jiang, committed self-abuse and died in an extremely cruel way, and the process of her death and the tragic scene were exactly the same as the content of the new work that writer Jiang had just sent to her. Not long after, another murder in a funeral home similar to the content of the comic occurred. Detective Qizhe (played by Yan Jijun) of the Bundang Police Station and his junior Jin Yongxiu (played by Kim Hyun-woo) intervened in the investigation and slowly traced back to the little-known background of writer Jiang. Ghosts are everywhere under the neon lights, and everyone has secrets in their hearts that they don't want to be known. Every grievance has its perpetrator, and every debt has its owner. Karma
