    Summary

    Post True Pacifist, "I want to stay with you" ending, and contains all the spoilers.

    After three years of blissful marriage, Undyne and Alphys have been working at Toriel's skill for most of those years, and Frisk is growing up into the ambassador they'd all dreamt they would be.

    After Alphys has a dream about Undyne cheating on her, she is convinced that it will come true. Undyne is sceptical - until the woman Alphys dreamt of suddenly appears as a new teacher for Toriel's school. Suddenly, Alphys is terrified that she will lose Undyne - and as a result, Undyne ends up feeling the same way for her.

    Co-written with GemR: full credit goes to her for the story idea, as well as a great deal of the dialogue. She doesn't have a screenname (yet), as this is her first story. Give her love in the comments, please!

    Please read the tags, absorb the warnings, then Enjoy!

    Summary

    Failure. Reset. Failure. Reset. Failure. Reset.

    This time, you fall into the Underground weeks before the 'Eighth' Human child arrives. But you’re not a child. And not many monsters expected to see an adult human in the Underground... not even Sans. You definitely aren’t supposed to be here.... or maybe you are? Maybe you’re the anomaly that can finally stop this endless cycle of resets?

    Or maybe you'll just get stuck in it with the rest of them.

     

    The “reader” is technically a young adult (twenties), female OC whose story is told through the second person. This was done to keep the story's POV similar to the game's POV.

    Summary

    She met Sans a few weeks before, and, subsequently, the skeleton invited her over for a small get-together at his house as a way of apology for an accident he caused. With puns and amazing food, she looks across the table and sees something not unlike what her own family would've done, feeling right at home here in the little family they'd made for themselves.

    A question sits at the back of her mind for the lazy skeleton, though, and the first chance she gets him alone, she's gonna ask.

    AKA, I literally heard the last time spoken in a dream and woke myself up laughing.

    Summary

    "Yeah. We'll free everyone. And with all this time stuff, it'll be like you were never gone."

    "But, be careful, okay? Make sure you come back. Even if it means giving up, stay determined to live, to come back. You're more important than the plan."

    ---

    A long time ago, a human fell into the Ruins. Confused and alone, they called out for help. But nobody came. The human clung to the shadows and hid in the dark. No one knew they were there for a long time. Like a demon, the human crept through the Underground. Until eventually, the human must have arrived at New Home. That's when we found out. Because... Asriel disappeared. No trace of him was left. Not even his dust. And once he was gone, the human left. The kingdom fell into despair. The king and queen lost their child seemingly overnight. The humans had once again taken everything from us. The king decided it was time to end our suffering. Every human who falls down here must die. With enough souls, we can shatter the barrier forever.

    You should be smiling, too. Aren't you excited? Aren't you happy? We're going to be free.
