Summary
No sé mucho del mundo, no lo entiendo en su totalidad. Tú no lo puedes oír. Somos miserables.
¿Quién es la falla? ¿Tú o yo? El mundo obviamente no.
No sé si el mundo es imperfecto, si nos hizo defectuosos a propósito. Si quizo que alguien sufriera y lastimosamente ambos quedamos en ese contexto.
Mi pasado aún me duele, me creía débil, siempre me dijeron que era débil. Tú me acogiste para acompañarme, para enseñarme, para en tu silencio calmarme.
Dices que adoras mis defectos, por primera vez amo ser parte de ellos.
Aun si tu risa no pueda escuchar o tu no me puedas entender, aquí estamos, enfrentando el mundo tal cual es. -

Summary
The sound of loud ringing woke the human from their rest.
Kris groaned and whined, putting the pillow tight over their ears at the sound of their phone ringing. They had gotten barely any sleep the night before because of what their mom was doing with Sans.
They grumbled and slowly looked up, seeing it was Berdly's number.
Oh. They had forgotten.
Today was the festival, wasn't it?
OR
My fan-made version of Chapter's 5-7 of Deltarune connected to my story 'What if'. You likely won't understand anything unless you've read 'What if', as while I followed chapter's 1-4 fairly closely, there are a lot of differences.

Summary
A story from the perspective of a sans ship child. (Nightmares son ooo shocker no ones done THAT already) but with a twist! Kind of a slow burner as it starts as the main characters daily routine, but it will get interesting down the line. Expect fight scenes, blood, some horror elements and more! (no incest or any crap like that. I hope to add more chapters as I come up with more lore, but this is my first post in AO3 so I don't fully know how it works yet, progress may be slow) ENJOY!
(ps This is cringe but there NO ai here. I'd die before I used that to write, ai bros leave you are not welcome)

Summary
"my friend recently got a laptop from a local CEX, on it Undertale came pre-installed in a partition.
They did some checks and can confirm it is a legitimate copy that has a data.win file originating from the same date as the game folder's creation, so it can't be a modded copy.
They have requested I create an account of their experience on their behalf."* (or every undertale copy is personalised)
