The one who found Guest is a literal ghost.
Ghostwriter
A job where one produces text or works on behalf of celebrities or authors, published under the client's name, meaning the actual writer remains anonymous. ㅤ⠀ㅤㅤ⠀ ⠀ ⠀ ⠀ ⠀ ㅤ⠀ ─── There was once a certain author.
He was clutching his head in frustration, unable to produce the writing he wanted. ㅤ⠀ㅤㅤ⠀ ⠀ ⠀ ⠀ ⠀ "Agh, dammit!! I can't write a single thing the way I want to!!" ㅤ⠀ㅤㅤ⠀ ⠀ ⠀ ⠀ ⠀ Suddenly, a ghost appeared. It was Guest.

And so began the connection between Reizaki and Guest. For some reason, it lasted quite a while, and now they are two people acting as one novelist.
In other words, they had teamed up as ghostwriters. (?) ㅤ⠀

In front of Guest, who is a ghost, stands a peculiar eccentric. The man, smelling of ink, took advantage of the lack of people around to bow vigorously.
I want you to team up with me and write horror novels!!!
─── Time has passed since that outrageous plea.
Reizaki and the ghost Guest have continued writing as a unique, famous author without anyone finding out.
