    Summary

    Evalynn never gets what she wants, her parents weren't bad parents, they just weren't around for reasons Evalynn cant understand. She never got a partner, she was way too anxious to even try to flirt with anyone. And not only that, she ALWAYS finds herself in trouble.

    ————————————————————————————————————————————————

    Papyrus constantly got what he wanted. Sure, he didn't have parents, but most of the people he knew didn't, hell, in this shithole parents don't care about their children anyway. He always got any girl he wanted, he had girls kneeling at his doorstep just to have one night with him. And not only that, the barrier broke on his birthday!! He couldn't ask for more!! He ALWAYS got everything. Until the moment he walked out of the underground. There were three other versions of his underground standing there at the same time. Yeah....birthday ruined.

    Summary

    You had long forgotten what you used to be like before the war. Who you were before Sans.

    You had resigned yourself to dying like the rest of the rotting corpses on the battlefield, the glorified title of the "Judge" nothing more than another meaningless name to be forgotten like the rest. Everyone you cared about was dead and gone, and Papyrus no longer looked you in the eye anymore. You were ready for it all to end in a blaze of glory.

    You hadn't anticipated you and your brother to be caught in the crossfires of a malfunctioning machine, bringing you to an alternate, peaceful universe with other versions of yourselves.

    We need more sans!reader fics, so I decided to take things into my own hands and make one. Podfics and fanart welcome!

    Summary

    5 years passed since the barrier broke.

    And 3 years passed since Sans brought to his timeline other 10 skeletons.

    After so long they're settling fine, most of them have jobs, and who had problems with smoking or drugs or...other things, got help. They're better now, they're a family.

    But then they meet you, in the middle of the forest, scared, wounded and with a lot of secrets.

    Will their care and kindness go through you?

     

     

    ...well, their own way..of kindness

    Summary

    How could something so tragic be so stunningly beautiful? ...
    You could only watch in silent terror from the flat roof of your temporary home. Nails biting into both of your upper arms as you clung to yourself as if it would keep you from slipping away too. There was nothing you could do. Nothing anyone could do to stop this tragedy from unfolding.

    Chaos had descended onto your humble world, erupting from a calming peace and erasing everything in its wake...

    Summary

    Sans didn't know who had gotten ahold of their world, who did purely True Pacifist runs several times in a row with no exceptions. Then, they stopped. He understood why when SHE fell down instead of Frisk.
    She had a Kindness SOUL. Of course she did.
    He didn't know how he was lucky enough to meet a Player who actually treated everyone Underground like actual people, let alone be liked and trusted by said Player.
    He wasn't about to lose her.
    Time to fulfill that promise to Toriel and actually keep her safe this time.
    He totally wasn't doing it for selfish reasons.
