This is just a collection of Undertale-themed one-shots that go along with the plot of my Sans x Reader fanfic, "When Two Souls Meet." It's a community project, and will have several entries from the winners of my one-shot contest, as well as some chapters written by yours truly. This can be read as a stand-alone group of one-shots, or connected directly to WTSM, as it is technically a direct continuation.

Y/N has been fighting chara for so long he doesnt gene know why he's trying. Until she gives up saying she can't keep doing this to him. Is this another one of her tricks? I do not own undertale or any other version of it or any vidoes or pictures I may use unless I say I own it.

[THIS IS A SEQUEL TO MY OTHER FANFIC "WHEN TWO SOULS MEET!" If you haven't read it, I would highly suggest it--the story won't make much sense otherwise.] Sans has finally found someone he can trust--Frisk's sister, the eighth fallen human. After months of step-siding and awkward interactions, the two are finally a couple. Things are slowly falling into place--there are no more resets, and Chara and Flowey have been a lot more quiet in the last few months. But things can't stay this way... can they? Note: The story was put on hiatus early on, and updates are now very sporadic. Despite that, it's still a labor of love!

It had been a couple months since your little sister went missing. Guess how surprised you were to see her on the news with the headline "Young Girl Helps Monsters Escape". When you meet the friends she made in the underground you can help but to love all of them, especially a skeleton with a love for puns and stars. Sorry I'm not that good at summaries X3 This is my first story so please tell me if I misspelled anything. I view frisk as a female so I apologize if you view them as male or both.

Monsters have returned to the surface, but that barely concerns you. Your only focus is to work and stay in control. Don't feel, don't lose control. You've spent years perfecting this practice and you keep yourself cold to anyone who stands in the way. A new employee at your work- a joking little skeleton - has a different idea for you.

This is a collection of chapters from my [Sans x reader] fanfic, Can You Hear Me? but from Sans perspective. Before reading this, I suggest you take a look at the main story, as this one will be based on the votes I get for the different chapters and probably won't make sense otherwise. It's been a few years since the barrier was finally broken by a human named Frisk, finally releasing the monsters back to the surface. They were all settling down well, finding jobs, learning about the surfaces history, and integrating themselves in the new culture that had started since their appearance. That's what most monsters were doing, anyway. Sans was a different story. Though he was happy everything had worked out in the end, and that the monsters were back on the surface, he was having trouble finding anything that really interested him up there. But that suited him fine, he thought, as long as everyone else was happy. That is, until he met (y/n). By some chance, Mettaton had been working with the rising star (y/n) Heir, and by another coincidence, dragged her along to one of the get togethers the gang had at Papyrus' house. That's the night everything changed for the group of friends that rallied around Frisk, and, that's also the night things got a lot more interesting for Sans on the surface. (Disclaimer on the cover: this is simply how I, the author, imagine (y/n) Heir. When I draw her, this is simply the design I use. Feel free to imagine her however you like, as this is a Sans x reader)

Monsters always fasinated you. Ever since Frisk broke the barrier and freed the monsters, humanity didnt take it too well but they are slowly getting used to it. Slowly. Very...slowly. (btw Chara is depicted as a female in this story, and so is frisk. Dun be triggy) HEY ALL! This is my first fanfiction EVER! so dont judge. [NC 16] at some parts :>
