A Tale of Dog and
by bones_of_a_rabbit
You're not a people person; could you turn out to be a monster person instead? You're a typical awkward human, except... for some baggage. You've come to accept that no one wants to deal with another persons problems, so you've become a recluse. When your new skeletal neighbor starts probing, you put up your shields. You don't want to tell him. If you do, he'll leave. That's how it always works. Isn't it?

A Tale of Dog and Monster: Gaster Shenanigans Edition
by bones_of_a_rabbit
It's been a long time since you've been this happy. You're in a happy relationship. You have friends that care about you. Your dog is okay. You are okay. You are even close to the man who no longer exists. Wait, what? Yeah, that's what his son has been asking. Who also just so happens to be your boyfriend. How is one supposed to explain how they're friends with a being scattered across space time when they're not even sure themselves? Could this end up tearing you apart? Could the truth be even worse then not knowing? (A sequel to A Tale of Dog and Monster; read that first otherwise you'll probably end up very lost.)

Daughter of Death
by Teutonic_lisp
(TOLD IN YOU/YOUR)A reaper, a few gods, and a bunch of skeletons. The life of a reaper wasn’t boring to her, everyday she would gather souls and lead them into eternal rest, and repeat.She watched creatures and Humans die, easily surpassing their lives and meeting once again in the underworld - or when she is evaluating their lives.One day, Y/N was told she was moving areas. A whole new continent in the world, in a city known as Ebott, where monsters had emerged from the mountain nearly five years ago. What happens when a workaholic with stubbornness to boot moves in the neighborhood, with skeletons causing havoc in her life? And, uh, well.. let’s say she isn’t the easiest person to get along with.*updated story description*
