That's all for the story arcs, both manga, webtoon, and anime. Unless the timeline of this book is changed, this is all I can do. 

I have started working on the chapter yet because I was struggling it would work out and I haven't got any good ideas from you guys which is really disappointing and depressing of me. 

If you have any ideas for the prologue, please let me know at the comments below or if you want to help me make this book a success. Peace out and enjoy!
