    Summary

    If Sans were being honest with himself, he probably could have run faster. He could have been smarter about covering his tracks, about making sure his scent wouldn’t be caught in the breeze, but with the apathetic haze of his depression riding him hard that morning, it was enough of a struggle getting out of bed let alone trying to take care of himself.

    The wide, white smile of the predator in front of him was a resounding affirmation of all his recent mistakes. “Hey there, sweetheart."

    In which Sans is a lost rabbit in a dark and dangerous wood, and Red is the hungry Fox that finds him.

    Summary

    Eight years after the barrier was broken, monsters are integrating well into human society. It’s taken a while to overcome the “kill or be killed” culture, but thanks to hard work on the part of the royal family - including a dedicated ambassador - things are finally looking up for monsterkind.

    Well, most of them.

    Without life-threatening danger to motivate him, Sans is surviving on nothing but snark and grim humor. He’s losing himself a little more every day, and nothing can stop it. Nothing except, maybe, a little girl who needs him more than either of them could have guessed. Too bad her mom hates him so much.

    Summary

    It's been 10 years since the barrier broke.

    I'm in a family full of monster-hating humans. But my soulmates are skeletons. And these said skeletons come from different lines of life. I know family is important, but hating someone, anyone, because of who they are to me is just plain...well, stupid. So if this means that I don't run my family's "business" then so be it. I'd rather love my silly skeletons than live in a family that hurts and ridicules others because of whom they are.

    But I don't think they'll understand as much as I'm hoping.

    Summary

    Suddenly, you were like a new toy. One I wanted to repair, to smooth the jagged edges off of. I did well. You became as docile as someone such as you could be. I helped you see that touch wasn’t bad. That it could be enjoyed. Slowly, ever so slowly, I was able to bring you out of your self-imposed exile.

    That’s when you met him.

    I should have kept you isolated.
