If a book is discontinued, this is most likely why. (Replace Undertale with whatever fandom this applies to.)
The reason why I've been writing about Vocaloid is because it's what I like right now. I want to finish some of these books, but because I'm not in the fandom, I'm afraid that I will forget some things about that character and the story won't be as good. This wasn't meant to be so long, but I had to get this off my chest.
