Its been 2 years since monsters where freed and so far everything was perfect. Of course it took awhile for humans to get use to monsters but nowadays everything's peaceful between the two races. 
One day Classic meets a certain skeleton that looks a lot like him at Grillby's. Will they become best friends or... maybe more? 

[COVER ART IS NOT OWNED BY ME]

Hey guys Firefox here! And I know how much of a flop attempting to write a fanfic was a couple months ago but I feel like I'm ready to try again. Plus there aren't many fanfics about these two and its my Undertale OTP aside from Charisk so... I'm gonna try this out!

College Letters [DISCOINTUED] by luciliri_

Sequel to "HighSchool SweetHearts~" please read that story first for you to understand this story!! I dont really know how to make desc. So here i go: Sans finally going to College called "Silver Gem University" or SGU, one of the most high-tech university ever. Sans wasnt happy since he has to leave his skeleton in red.. It really shatters him but he will visit once a while, It was a 5 hour trip to go there so he just looked out the window, what nice skies. He was about to fall a sleep until he saw some one sat across from him. He looked up and this monster was a cat monster not quill, but he did look almost alot like her, blonde hair but a bit darker wearing a purple jacket and white shirt that has the youtube logo on it. Well i guess i should say something to not be rude. I would feel uncomfortable to if someone just stares at me without a word. "Hi im sans, nice to meet you!"

Sans x reader (together) by Gabbylabby123

Hiya! This is going to be my first fan fiction. I have recently been obsessing over undertale, and sans is my favorite character. I have already read a lot of sans x reader and decided that's what I wanted to write. I don't know how long this story is gonna be or how often ill update, but ill see how it goes and if you guys like it I might do more in the future. XD wish me luck! Ps. I do NOT own any artwork that may be used.

The life of the skelebros by lili_bugg

The young skelebros escape from the core and head to Snowdin. Grillby finds them decides to take them in but finds out it may be much more difficult than he thought. Papyrus likes Grillby but it takes Sans some time before fully trusting him and even then there are things that he doesn't want to share. Although Sans struggles with his magic and with meeting new monsters. But, he's able to find some close friends when situations get rough. Ik my art is kinda weird but it was mostly just for fun. I'm definitely no artist. All art is still mine tho. I won't edit much here. Fully edited story on Archive of Our Own. Same name as here.

Hot Stuff || BOOK ONE. by Flamogedeon

- Long story short: You climbed up a mountain, you fell into a hole, and you didn't bother going back to the surface. And why is that? Because of this hot stuff. - I'm pretty sure the cover says it all, don't you think? And I'm pretty damn sure that THIS is long overdue!! Aww, yeah, baby!! This fire-baby needs some love too, y'know? So without further a thou, I present to you, a Grillby x Reader book. *insert majestic exit* See ya. - EDIT: Quick Disclaimer, y'all. The photo used in this book ISN'T mine. No big shocker there. It belongs to its RIGHTFUL OWNER. Frankly speaking, I found the photo on WeHeartIt. Check it there if you want, I guess? Anyway, hopefully, I don't get sued by this. See ya.

The Verte-Bae ~ A SansxReader~ by Melady605

Humans and Monsters have been living together on the surface for a while now, but humans still don't seem to accept them in the community. Not all humans accept monsters, and now they are treated as low lives. You are a human who lives with your adoptive monster parents, and you can't understand why no other human can see how pacifistic they really are. After going to your favorite diner, Grillby's, you meet a monster who has the potential to change your life forever. Will the encounter be fate, or was it the mysterious pun master's intention?

From Darkness, Love Came Through by FinleyLivesInTheVoid

A long KingDings fic because this ship does not get the attention I think it deserves. I love this ship, and it's adorable. I plan on making this a full story, so buckle up! Also in this Gaster is Sans and Papyrus's father because Dadster is wholesome and cute. Toriel and Asgore are decent friends in this one because I believe that they could have a friendship if they tried. I will put in little bits of my other ships, but Asgore and Gaster are the main focus. If you want the actual story, read it. It's very fluffy and cute and gay. If you follow me, I know you like the gay ships.

The Fallen One by NinjaGamerGirl333

You have fallen into a strange world... will they be friend, or foe? This is an underfell story, so I hope you enjoy! Also, I will be using the pronoun she, but for all the male readers, just replace it with he. Sorry if this is an inconvenience, I just think it would be easier to write that way. Y/N ~ your name E/C ~ eye color H/C ~ hair color S/T ~ skin tone Leave a comment, and share this story! I will try to update at least every day, so there will be almost no wait for new chapters. ~NinjaGamerGirl333
