I Work Part-Time in a Ghost Story Novel

Millennium background + horror story + weird part-time job (There is a female protagonist, and the male protagonist has cheats but no obvious cheating) Cao Yunyang, an unemployed young man who lost his job after graduation and hung up walls in a rental house and wrote online articles, woke up in a strange room after experiencing sleep paralysis. He was indeed wearing the book, but before he could open the champagne, he was horrified to find that he was actually wearing the weird novel he had just read, or the good friend He Yi who had received the box lunch in the first chapter. The plot has just progressed and He Yi has a few lines left before he is about to leave. How will he avoid the murderous intention? Try sleeping in a haunted house, night shift security, community property, and fishing for corpses in the water. What kind of dilemma will he face? Don't you want a job? There are plenty of them here! Wait, what do you mean the male protagonist kills the ghost?
