Summary
I don't know much about the world; I don't fully understand it. You can't hear it. We are wretched.
Who is the fault? You or me? The world, obviously, isn't.
I don't know if the world is imperfect, if it made us flawed on purpose. If it wanted someone to suffer, and sadly, we both ended up in that situation.
My past still hurts. I thought I was weak; I was always told I was weak. You took me in to be with me, to teach me, to calm me in your silence.
You say you adore my flaws; for the first time, I love being part of them.
Even if I can't hear your laughter or you can't understand me, here we are, facing the world as it is.

The curtain has fallen.
An entire world, your world, brought to ruin and ultimately sacrificed for the well beings of a family of grieving gods. Your family.
You are left alone with no hope to hold onto.
You've resigned yourself to this empty life. Left the wishes of those who are gone unfulfilled.
But. Are you really giving up? Will you let this ending be yours? This ending that was forced on you, won't you rewrite it?
The pen is there for the taking.
It's time to go home, Partner. And remember. Stay determined.

Summary
Small Disclosure:
This is an Undertale fanfiction written as a romance with Sans, (Sans x Reader).
(Your name and description will be provided for you as that is easier for me to write).Description:
It's all so boring. Life is nothing but wash, rinse, repeat everyday for Dae. She has experienced so many things- has felt so many things. But has she? When she's alone at the end of the day she's still stuck with one feeling- emptiness. Her whole body feels it. That something is missing. Thankfully, it doesn't affect her too much until those late night hours- but it still does- as well as one other thing...
Fear.
The feeling that persists even with the emptiness. That emotion- if not mildly inconvenient at times and unpleasant- was the one she could feel the most at times.
Maybe it was chasing that feeling that pushed her up the mountain that night? Something to stop the feeling of nothing from spreading throughout her body.
But clumsy is she who pays little attention to her feet.

Summary
An Angel scorned, with tears of fire;
The bitter path, of thorny mire.
All countdown to the Earth's expire.A soul of Justice; borne true and bright.
One of Compassion; with monstrous might.
Usurped from deepest, darkest black;
A Prince of hollows, bearing lack.Two Hearts;
Two Ends.
They play their parts,
In rage-wrought bends.
From burning vengeance, a twisted boon;
Faux transcendance, of DELTARUNE. -

Summary
So, the general idea of this fanfic is that Chara never commits suicide and because of it they are still alive when the other humans come to the Underground.
They still hate humanity, but nevertheless aren't willing to commit suicide as they don't wish to leave their family behind, even if that selfishness means Monsters remain trapped in the Underground.
Then four years into their era the second of the eight humans arrives to the Underground, the one who arrived didn't trust Monsters and had in fact come to confirm whether the first human was dead, the fact that they weren't may be the only reason some peaceful resolution can be attained one day...unlikely, however.

Summary
A collection of stories, either following a timeline or veering away from it.
Alphys and Sans worked together a long time ago. They even dated once, and were madly in love with each other. Then, they discovered important parts of their identity, and decided to break up so they could pursue their true selves. They're in the middle of wingman-ing each other when an incident happens, and they decide that, for the sake of their friendship, they need to part ways. They don't forget each other, though. The romantics may be gone, but there's a stronger kind of love in its place.
This is the story of how their relationship has changed over the years, and also how it stayed the same. Lots of different things happen, not in order or in only one timeline, and it doesn't exactly end. If you want something that makes you happy, click here. If you want something that makes you sad, click here, too.
Updating periodically... no set schedule yet!

Sans wakes up, that part is not out of the usual, living things usually do that after they sleep, the weird part is that the human hadn't restarted the timeline, because if they did, he wouldn't remember everything.
