Summary
“Not so fun being stuck in some loop right? Trying to fight to protect what ya got, not getting a choice in it. If I had the choice I wouldn't remember either.” The words oddly felt comforting. Link let out a slow breath, closing his eyes for a brief moment.
He didn't feel alone for the first time in a long time.
And that?
That was terrifying.
“To be honest, I kinda gave up a while ago. Just sat back and let the chaos go on, felt like nothing I did mattered anymore. Everything would just be reset anyways. Stopped caring what happened, that was until you showed up.” The skeleton’s eyes bore back into the Hylian.

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.

Summary
Hace tres años, alguien reescribió la memoria del mundo.
Los humanos y los monstruos de Ciudad Ebott conviven en paz, unidos por una fe común: la Iglesia Omni, cuya figura central es una mujer de hábito blanco que cubre su rostro. Nadie recuerda por qué empezaron a creer en ella. Casi nadie recuerda que hubo un tiempo en que esa paz no existía.
Casi nadie.
Mientras tanto, el multiverso arde. Universos enteros desaparecen. El caos avanza sin que nadie lo detenga.
Y UnderOmni lleva tres años sin aparecer en ningún radar interdimensional.
No fue un accidente. -

Summary
Frisk completes her first journey through the Underground on the True Pacifist Route, freeing the monsters and helping them reach the surface. With Toriel and Asgore working together to build a new home for monsterkind, everyone begins adjusting to a life they’ve only dreamed about.
As the months pass, Frisk grows especially close to Sans and Papyrus. What begins as lazy afternoons, terrible jokes, and countless adventures slowly turns into something neither Frisk nor Sans can quite explain.
Curious about the Underground’s past, Frisk starts asking questions. Innocent questions. Questions about timelines, resets, and the choices that could have changed everything.
Questions Sans has spent a long time avoiding.
As old wounds resurface and buried truths come to light, Sans must decide whether he can finally tell Frisk everything he knows. But the closer they grow, the harder it becomes to keep his distance.
Can their feelings survive the weight of countless timelines, or are some secrets better left buried?
