The series- First book: "Lost in Despair" -Finished Second book: "No More Time" -Currently writing Third book: "Can't hang on" -Work in progress ---- You were already insane, sure. But now that the voice inside your head gets louder, so does the one in Sans' head. It's like you two, the different couple, are always targeted. Why couldn't life just slow down for a bit and let you live for a while? No, not enough time could change the decisions you've made, or the ones you will make. Your life is like a book that's being written. You never know when the ink could be smudged or the words at the end of the book are not the happy ending you hoped for. Not everyone gets a happy ending. ---- "Every book doesn't have a happy ending." ----

It was a simple created monster soul, until it grew legs and was given a new life. There will be swearing and other explicit content. Please don't read if you can't handle reading that stuff. I will update this after adjusting a couple of chapters.
