Summary
Two days ago, you said goodbye to your best friend. Yesterday, you lost your job with no prior notice. And then today, you had a fight with your mom. So that’s your day today. Lonely, fighting with your mom, jobless. Perfect Day for a drink or two, right? What's that on TV about monsters?
You didn't expect the monsters to accept that application for a social media job you sent them while you were drunk. Now you've suddenly moved to Ebott and spend your days hanging out with monsters, documenting your weird new life, and marvelling at how different monsters and humans can be - and how similar.

Summary
You had forgotten what you used to be like before the war. Who you were before Sans.
You resigned yourself to dying like the rest of the rotting corpses on the battlefield, glorified title of the "Judge" nothing more than another meaningless name to be forgotten. Everyone you cared about was dead and gone, and Papyrus no longer looked you in the eye. You were ready for it to end in a blaze of glory.
You hadn't anticipated being caught in the crossfires of a malfunctioning machine, bringing you to an alternate, peaceful universe with other versions of yourselves.

Summary
"You never know." You shrugged and flopped down on the grass beside our oak tree. I lay down beside you, letting your arms drag me closer and wrap around my torso. Our chests rose and fell in tandem. Above us, the stars stretched far into the pure black sky. They seemed to be shining brighter than ever.
A series of letters written from human Spamton to monster Tenna leading up to the Human-Monster War

Summary
Long ago, two races ruled over Earth: Humans and Monsters. Religion and fear of differences troubled the fragile peace on which both species were living so far. A war for faith and honor soon engaged between them. Long. Endless.
Sans and Papyrus, two young skeletons brothers, sons of the Royal Scientist, lost everything in the rage of the fighting: their home, their family, their childhood. During a human attack, they suddenly found themselves delivered to bullets and bombs, all alone.
Both of them started a journey in the devastated landscapes of the end of the war to join Mont Ebott, where Monsters are preparing for a last battle. But could two kids survive by themselves in the wild and without any help?

Summary
[Honestly..
After everything you've been through you didn't expect to find yourself here, in the middle of a fight between two men you recognized too much to be normal, with your unconscious husband in your arms having a near death grip on both newborns while you could at least stand without feeling your legs numb.
You lost hope of being able to hide when both turned to look at you and your dear still sleep in your arms, whom you quickly hid from sight with your cloak, covering him as much as you could.
"Fuck.."]
Or; After years of being responsible for making the impossible possible in a crumbling world, your people receives an unexpected but not less welcome peace. You don't plan on freeing your claws from this chance.

Summary
A story that narrates the adventure of a young woman and her new Human — but also Monster! — friends. She wants to be able to give everyone the Happy Ending they all so crave.
They need help in ending this Sorry Tale before it is too late.
ᯓ★
He asked you why you betrayed him. His breathing was ragged, and his hair did not have the same pleasant odor of coconut oil and wheat that you had grown to love. It was musty, reminding yourself what kind of monster you had in front of you.
Not a Monster, but a monster.
The meaning of his name didn't carry his personality anymore.
"... Ironic, is it not? Since I am not the one who is holding a dusty knife right now."
