I finally finished it. Some of the plots in the middle are in the extra chapters of another book, but I will work hard on when to do it (because the other book is really long...)
The extra chapter of this book... Is also after the other one (don't ask why, it's because I wrote it after that book when I was writing it, in order)
However, the endings of these two are not BE (see another book for details)
Purpose: to supplement the plot
