    Summary

    Once upon a time Humans and Monsters went to war.
    Once upon a more recent time Papyrus' brother Sans got a promotion. And now Papyrus was off to buy him a human toy, pet, simple plaything to fuck and to kill...
    Humans and Monsters. That was all that was important. Humans and Monsters. Just supposed to be a week of fun. One's hell being another's heaven. Humans and Monsters. It's just the way things go. Her hell, their heaven.
    ....... but something's wrong.
    It's not the way it goes at all.
    And you may think the worse person can't change because LOVE and hurting are a cycle and the more you hurt the easier it is to hurt.
    But in the end, hope and Mercy are too.
    You just have to keep finding ways to stay determined.
    Even when it seems impossible and hard, and Mercy apparently seems spent.

    Summary

    Edge twitches, his soul skipping a beat, but before the tone could die out, he is by the desk, pressing it against his ear. “Private Detective Edge Serif, how can I help you?”

    “My name is Blue Fontaine,” a light voice with British accent says on the other side of the line, sounding incredibly serious. In the background, he can hear something that sounded like quiet sobbing. “I am calling on the behalf of Sir Razz Gaster of Duskshire Manor. We have heard of your abilities and we require your assistance. Sir Razz’s husband have been found dead.”
    ...
    A late night, after yet another unfruitful day with no work, Detective Edge Serif receives a phonecall from the countryside. There seems to have been a murder.

    Summary

    You're just trying to live your life peacefully with your childhood feline while being no higher than 12 inches tall. Life is actually decent for a good stretch of it! Too bad it'll crash around you.

    Cool. Great. Yup, just what ya wanted. Double thumbs up.

    And by that? You mean that the home you have called yours has been sold off to these oddly similar looking skeleton brothers.
    Now you have to find out either a new place to run off to, or try and persuade these Monsters to allowing you to stay for at least the winter.
    Let's hope they're nicer than Humans...

    Being a bitty is tough work as it is, now you have more work put on your shoulders.
    Oh, lets not forget your memory sucks and is so screwed; You're rather unhinged and probably insane.

    Being alone for so long out in the woods would do that to a Bitty, you know! Let's hope it all works out in the end.

    Summary

    Hello Dearie,
    If you’ve found this note, you’ve probably found my friend with it. He’s been hurt a lot, and he isn’t getting better here. If you can’t help him, or if this isn’t your handwriting, please pass him on to the nearest Muffet. She’ll know what to do. Thank you so much, dearie, and I hope your life will go better than mine.
    Cordially,
    Muffet
    P.S. His name is Sans, and his favorite food is ketchup.

    Summary

    You felt a fire in your chest, a tug, a pull.
    You knew you had to go.

It's safe to say that you get more than you bargained for when you witness the murder of your monster neighbors by a secret anti-monster organization. It's a desperate situation for monsters as your testimony might just let them get a shot at basic rights. you’re placed under witness protection and must adapt as your life suddenly is turned upside down by not one, but two extremely rude and incredibly dangerous skeletons.

    Of course, your new bodyguards did not count on you being their missing soulmate.

    Summary

    Something felt wrong being here.
    Watching the tiny beings scurry and bustle about in their pens,
    Some were lethargic while others just waited by the glass with a hopeful aura.

    The hope and wonder in their eyes felt out of place,
    The pressure began gnawing at my chest.
    I left the pet store empty handed that day.

    "Have you ever heard of the Itty Bitty Rescue Y/N?"
