Summary
It was hard to explain, exactly.
A feeling. Walking into his room and his clothes not being where he left them, the bed messy and unmade. His favorite seat having a new indent in it. Mostly-empty bottles of condiments in the fridge, a spare pair of shoes by the doorway. A glimpse of bone as he walked up the stairs. His brother talking about things that Sans didn’t remember. Hearing people use his name for someone else.
A ghost living in their house.

Summary
**ON HIATUS**
"Not one human that falls down Mt. Ebott comes back."
But you did... though not unscathed.
After succumbing for the first time to the wrath of Toriel, you wake up to the sensation of something growing on you. A golden flower trails the contours of your face, right where the goat dug her claws into you. While gazing at your reflection, your fingers follow the tendrils of its roots carefully. A display of your untimely death staring back at you, yet you were here anyway.
A cryptic buttercup by the name of Flowey guides you through the catacombs of the Underground, latching onto you like glue in hopes to also escape. As you travel through the caverns, you realize that teaching the monsters mercy may be harder than you initially thought. Despite this, you're not one to give up so easily. Forming an alliance with a certain skeleton turns out to be the best mistake you've ever made.
**flowerfell does NOT belong to me! this is just my take on the story since i found it very intriguing.**

Summary
I don't know I got bored. Mostly just me rambling into a word document. Don't expect much from me. Serious lower your expectations. Or F chubby Reader insert x Underfell sans where reader is an art professor in college at Ebott city. Reader likes to draw things from life and finds herself regularly going to parks and cafes and..... stuff ensues following these actions. Sans is a mechanic. Both are broke. This is about reader being inspired by real life and enjoying what there is in life. So... yeah no this isn't going to be a fairytale with her finding a random dude (Sans) and him being rich and reader becoming a sugar baby. They both work jobs that don't make them rich.

Summary
Papyrus had never been the type to get drunk. It was unprofessional, especially for his status as Lieutenant of the Royal Guard, and quite frankly, not his thing.
However.
How unprofessional could it be when his boss (Undyne) challenges him to a drinking competition to see who could drink more? At her birthday party no less? Nothing could possibly go wrong.
That's what he believes until he wakes up the next day with a pounding headache and a picture of him (he shivers just thinking about it) cuddling with Mettaton, the biggest nuisance of his entire life. In his camera roll.
What. The actual. Fuck.

Summary
The streets are rough this time around in Ebbot. Winter has never been easy. However, this year, just looking for food or asking for spare change became a lot more difficult. There was already snow on the ground before halloween even came around the corner. It was going to be a white Christmas for sure.
Although. You don't think you will get to see it.
Your body was running on fumes. And you knew it. You could barely walk down the alley to get to you make shift home in that abandoned building. You face plant onto the frosty ground. Too tired to try and get back up again.
Your brain was pounding against your skull. A silent threat of smashing it in order to touch the cold snow on your face. You move your face up, ever so slightly to breathe the air. God it hurt your lungs. The winter air, snapping the back of your throat with a scratchy feeling. Before, death was welcoming, however; Not now. You did not want to go back Underground to face Sans in that hall.
Not again.
So you did the one thing, you never thought you would do.
You call for help.
...
....
......
Someone heard your cry.
