How Could I, a Social Creature, Become the Protagonist?

My name is Tang Qing, and I am an online writer by profession. I wrote a book called "Infinite Mirror". However, the data of the book has been poor, and the manuscript fee is getting lower day by day. Seeing that life was about to become unbearable, I had to give up writing this book. After a long time, my income gradually increased, and I opened this book again. But I was surprised to find... My book actually updated automatically. The characters in it actually have thoughts of their own! They continue to develop and grow... And the protagonist in my book is Chen Jie. I can't find him... Slowly I can no longer control them... These hateful NPCs, how dare they resist my orders! "Li Po... Go kill them..." "You are the only protagonist!!!!"
