If a Fujoshi Were Reincarnated into the World of a BL Novel She Created

I came up with a random setting as a pastime and decided to expand on it. It's a BL novel conceived by an ordinary person who was nothing more than a casual fujoshi fan, not a famous author, who is reincarnated into the world of the BL novel they created themselves. Since the settings and other details are somewhat loose, please read this with an empty mind.
