warning; this book will mention depression, suicidal thoughts, anxiety/panic attacks, depictions of violence, and other things that have happened to characters. I will put a warning at the beginning of a chapter. At the beginning of the part where it may become triggering, I will put some sort of divider, whether it be an emoji or a bit of bold text. At the end of a chapter with a triggering part, I will put a short summary of what was said/done in the part in a non-triggering manner. I will not tolerate hateful/offensive comments, they will be deleted.

disclaimer; I own none of these people because if I did it would be weird. I do own the plot (except the main one for Detroit Become Human). I have never been outside of the United States, so descriptions of countries may be skewed/stereotypical, and I apologize in advance. I also apologize if descriptions of Disassociative Identity Disorder are incorrect, as I do not personally have it but I've done as much research as possible (Shout out to The Entropy System on YouTube!). There will be the usage of words I may not understand (mostly pertaining to science) so I apologize if I get them wrong.
