Want to talk about falling into the wrong place at the wrong time? Y/N definitely scored big time on that one. One moment she's falling, the next she finds herself trapped underground with a monster that wiped out his own kind. He's a cold-blooded killer that never shows any emotion. Though, as time passes, she finds out that Sans isn't as heartless as he plays himself to be. Hello! Writer~San here! Cover art and Undertale AU/Characters aren't mine, but the story definitely is. I hope you enjoy it!!!!
