Summary
Sans looked at the ceiling in pure boredom, unable to sleep as he listened the guards opening the gates of the inmates one by one. It didn't take long for him to hear a guard slamming his club against the bars of his cell.
He'd been told a doctor wanted to do check up on all the inmates, so he didn't really question it when he was forcibly pulled out of his cell so early.
Being pushed around wasn't fun, but at least it was exciting to meet new people that weren't convicts. They had a tendency to be assholes and not appreciate his humour anyway.
"Sans?"
He saw you, with half on your face covered by a mask as your eyes squinted in curiosity.
You were looking at him so intensively, it almost made him feel uncomfortable.
"Please, have a seat."

Summary
You didn’t really care, they were just distracting you now, distracting you from the sea of stars above you, your hand lifting of its own volition — the stars shine, just out of your reach.
One foot lifts, the heel falling away, clattering noisily to the floor, your toes pressing daintily to the terrace’s railings, bracing as you heave yourself up to stand, skirts billowing and flowing and flying about your body as your remaining shoe falls away as well — you extend your hand again, curl your fingers like you're shielding a small, shivering flame from the soft brushes of the wind.
The stars shine, just out of your reach.

Summary
You're a grad student at a house party. How many skeletons are you running into there? At least one you didn't expect.
(This explains nothing. Please read if you like Sans/Reader romance slice of life with plot, character relationships, fluff and eventual smut. Underfell headcannon is being used.)
(Time for a second note to reemphasize PLOT. Drowning in plot. Plot for days. Send help.)

Summary
When you were ten years old, your parents sent you to stay with a relative of yours from Ebott. Their villa was situated up on the mountainside, and you loved to explore the forestry. One day the ground gave out and you fell Underground, and faced terrors beyond your imagination. You were missing for weeks.
After you managed to miraculously return to the surface, your parents were relieved - but deeply troubled by your 'delusional ramblings'. They were convinced you were 'crazy', and feared how that would reflect on their reputation. Your doctors advised sending you to an in-patient psychiatric facility, which is where you spent the next few years in intensive therapy and counseling.
15 years later, you're a young adult with a somewhat manageable grip on life. You keep your head down, attend the social events that are expected of you, and try to be as unnoticeable as possible. Your parents arranged a suitor for you, and you're to be wed within the next year.
That is, until, those monsters your parents and doctors tried to convince you weren't real suddenly crawled out from the Underground. And they're a lot different from what you remember.
