I Wrote a Script to Kill Me, but a Vicious Ghost Came to Visit Me

The protagonist, who was once a screenwriter, travels to a world where humans and ghosts coexist. People in this world will contract a ghost of their own when they turn eighteen. When I was eighteen years old, I only contracted a loli ghost with no lethality. But it doesn't matter, the protagonist also gets the script killing system. As long as he writes a script and gets good reviews from customers, his loli ghost will become stronger. So the protagonist followed the actual facts closely and wrote his first script, Killing the Abyss Horror, with Mr. Ke as the theme. What the protagonist didn't expect was that his first guest was not a human but a ghost... This novel and its characters are purely fictitious.
