Summary
Your name is unimportant. Your job is nonexistent, really. And your (ex)roommate just kicked you out in the middle of a surprisingly cold November night. But whatever. You don't care. You'll be fine.
Keep telling yourself that as you freeze to death, idiot.
But you'll be fine, for one reason! Two, actually. Two people - monsters really - who just so happen to have the same names as some fonts you know of? You stay with them instead, just to get back on your feet, and a single question rises to your mind.
What the hell is keeping you here?

Summary
You recently moved into this mansion, and a few days after getting all the stuff over, you have a thirst for waffles, but you don’t have sugar at home! Unable to wait, you walk to the neighboring mansion a couple minutes away, and find some things (more like a couple someones) that shake up your new life. Who knew there could be so many skeletons in one place, right?
Or…

You’re a 23 year old who’s been living in a mansion you inherited from your Grandmother for a couple of years now. Your days consist mostly of chain smoking, drinking, sleeping, and scrolling. The house is huge, dark, and lonely. One day, out of pure boredom (and NOT loneliness) you post an ad looking for roommates.
ROOMS AVAILABLE— BIG ASS MANSION (no creeps)
What could possibly go wrong?

Summary
It’s fun being dead.
Or undead, rather, as your sister likes to correct you. Your dear sister is the kind of person who took her dark arts very seriously. Or, her necromancy, rather. You’ll be the first to admit, you don’t know a lot about her school of magic. She doesn’t know much about yours either, but it’s always enjoyable to discuss magical theory with her. She says it’s not her specialty, but she tends to under credit herself.
Or: A remixed spinoff story of this_is_my_alt's The Sacrificial Skeleton and the Labyrinth of the Gods <3

Summary
Papyrus thinks he’s being kind. He thinks that by ending your brief, beautiful "situationship," he’s sparing you from the wreckage of his own guarded soul and the threat of Chara's power. He’s trying to prevent a loss that hasn't happened yet.
Now, with three other timelines crashing into theirs, the Underswap brothers are no longer the only ones in the house. As the air grows thick with magic and protective instincts, Papyrus realizes that "letting you go" was a lie he told himself to survive, but when he's ready to take you back it might just be too late. -

Summary
Ever since you were granted a mysterious gem as a young student, you've been given the gift of being a Magical Guardian, protector of Justice!
For a while, your powers weren't really needed..so you mainly focused on living your daily life.
..At least, until some edgy skeletons came crashing into it.

Mainly intended to be a comedy/unserious, but there are also good amounts of lore and seriousness at the same time. It's like 50/50
No consistent update schedule, I just kinda add onto this when I feel like it, I hope you guys enjoy!
