Summary
You babysit Frisk for extra income whenever Toriel has to stay working later hours at her new school for monsters and humans.
Until, one day, she calls saying she can't make it, and that someone else will come to pick them up.
That's when you meet him: a skeleton monster looking as haggard as a shipwrecked man, and smelling of smoke and booze.
You offer him some dinner and a cup of coffee over some small talk, and then, he gets comfy on your couch.
It feels bad to ask him to leave, so he ends up staying the night.

Summary
A stand-up comedian with a bad temper and low motivation ends up falling for Frisk's homeroom teacher, her irritatingly soft voice, and her smug attitude.
Who would've known?
There's probably a lame old joke hidden in there somewhere, but he doesn't give a damn about that right now, so maybe come back later, and he'll think of something.
(Mostly told from his perspective, but there will be chapters featuring Second Person POV.)

Summary
You fell into the Underground as a child. You spent a few years there, growing up with the skeleton brothers. Life wasn't great, painful at times, however you had your family with you.

There were too many factors. Monsters were there that you couldn't be around. But maybe.. some can help you?

Summary
The world was turned on its head when monsters emerged from Mount. Ebott. Not only because of the whole other civilization that laid forgotten under the mountain, but the magic that was released with them. It didn't just change the world, it changed the people. Literally. Over a third of the world's population turned into monsters, horns and fur and tails sprouting from their skin. The lucky ones were further away from the mountains, their turning being gradual and generally painless.
You were unlucky enough to be in Ebott City when the monsters emerged. Your turning was recorded as one of the worst cases, turning you into a skeleton. The turning was so bad that you had stayed behind in the converted mental hospital for a full year, learning how to cope and adjust to your new form.
You can't stay forever, though, and it was now time to go out, to be released back out into the real world. It was time to get back to it. And you had a very generous house of monsters ready to welcome you in and help you get back onto your feet.
Content/trigger warnings will be at the start of every chapter if they apply.
