    Summary

    It's a constant struggle to survive amidst the cold uncaring stars. Especially when said stars keep trying to kill you. After Papyrus's fleet is flung into another galaxy, you're forced to adapt to the new dangers. Everyone wants to go home, back to the Milky Way. But this ship is your home. When desires and flaws clash, the challenges reveal who will thrive in the hostile environment and who will be left behind in the vast expanse.

    Updates Tuesdays and Fridays (8pm-10pm EDT). I finished the entire story (!!!!!), so this won't be abandoned unless I randomly die of coronavirus. Stay safe, y'all. (There's not enough good, long Papyrus/Reader fics. Here's my go at fixing that. This is the second draft of a work I finished last year, but it's improved and different in many ways.)

    Summary

    Sans found a massive, purple door in the ruins, and the voice behind it told him to protect the next human that came out.

    It was the first human he promised to protect.

    It wasn't the first human he saw. It wasn't even the first human he protected. The rest of them just had... less happy endings.

    Let's see those endings.

    Summary

    Everything keeps looping. Sans doesn't remember.

    Except when he does.

    It's quite inconsistent.

    But, either way, he knows one thing. There's something up with Papy's new best pal.

    Summary

    You were suddenly released from that... hell, without context or explanation. All you want to do is keep your friends safe, from yourself and other forces. And then, skeletons. So. Many. Skeletons. Let me tell you, keeping the fact that you're a mage is a tedious job already, but now with boss monsters thrown into the mix? Things might get harder for you, yet nevertheless, you should always keep your guard up. Who knows, perhaps..

    Summary

    Underfell... el peor lugar para encontrar el amor, para vivirlo y ocultarlo. Papyrus y Sans no son la excepción, una historia en donde hay mucho dolor pero también momentos gratificantes. Totalmente Foncest y hecha para sacar los pañuelitos desechables. Lean primero la etiquetas y trataré de poner advertencias en los capítulos que lo requieran.

    Esta historia ya está publicada en wattpad, pero la estoy pasando aqui para compartirla aún más, es mi primer fanfic escrito y trataré de revisarlo para que no se quede con las fallas ortográficas que se pudieran haber quedado en el trabajo original.
