To save the world of online fiction from being polluted by authors who keep abandoning their stories, readers band together and force those authors to become idols.
One of the Coo-Coo Idol Project's initiatives, and its most successful one, is Coo-Coo GO, a big-budget game made for readers. They can draw the authors they wish they could lock away in a little black room through random gacha pulls, then treat them however they like.
For example, they can transform an author and make them transmigrate, send them on adventures in another world, make the plots the authors wrote happen to them, or dress them in bizarre outfits and make them do bizarre things. In short, as long as it's an author, readers can do whatever they want with them.
Readers can also make videos or write stories about how they toy with the authors and share them. This book is one such story.
It's about an author who left too many readers hanging, and was cursed to transform and transmigrate.
