Are There Any Korean Entertainment Novels?

Can I Write Fan Fiction About the Korean Entertainment Industry?

I don't know much about the Tomato platform, so I would like to ask if you can write fan fiction or derivatives?

Asking for Books! Korean Entertainment Female Channel

I want to read a book similar to "Korean Entertainment: The Winner System of Life". Are there any books of this type, where the heroine is a solo character who doesn't join a girl group, is a playboy and a womanizer, and is about Aquaman and a scumbag? It's best if it's systematic.
