    (First Undertale fan fiction, so it'll suck. Sorry, but hopefully you don't have too bad a time reading this. As I add on, it might contain fluff, but no lemon smut, so this isn't that kind of fan fiction, sorry) Frisk is now 18. It's their birthday, and their last day of high school ever. Everything looks great, except everyone goes back in time. Someone is resetting the timeline, and it's up to Frisk, with the help of their boyfriend Sans, to make it right, or the biggest danger will be released: Chara. Can they do it? Or will Chara come out to play? Find out in "*Stay Determined"!

    This is based on the video game Undertale by Toby Fox. This may contain references and other things from the game that you won't get unless you've played it. Summary: What if Frisk never left the small town of Snowdin, and instead chose to stay with Sans and his brother Papyrus? P.s The amazing artwork I put in this story isn't my own.

    This is Undertale related so go check out the game or some comics, if not, then you will not understand most of this...cause this includes a murderer person, Chara. While fighting Sans, Frisk caught him off guard, and ended him. Frisk, being who she is, cried and tried to help him. As Sans was about to turn to ash, he said something, "I'll be fine kiddo. Just reset everything will be fine, I'll make sure. Hopefully the next timeline isn't....cat-astrophic." Yes, it was a pun intended...but didn't it seem more like a warning, or a call? But is was. Instead of there being two brothers, there are three, but one a girl. Everyone is a type of animal, even the skeletons. Gaster is in eager of getting revenge on Frisk. And Chara, she's good, and a mouse? Everything was different, who made this happen? Was it Chara? Did Frisk do something wrong? Did Gaster effect the timeline? Who?

    This story is going to be an AU that I'm creating. It is about the war against the monsters and the humans long ago. And what it would be like if the Undertale characters such as Sans and Frisk were in the war.

    A human girl named Frisk, was curious about the hole on Mount Ebott. As soon as she got to the top of the mountain...she fell in. Then she will meet the creatures of the underground and maybe they might change her mind about her choice. These characters don't belong to me. They belong to Toby Fox. I'm just using them for my story. Also in this story, Frisk and Mettaton are girls. If you don't like it, I suggest you don't read it. - Rosu

    Frisk has just saved the monsters from their impending doom underground. Perhaps it was fate? Maybe Frisk was meant to fall underground with nothing but Monsters around. Or maybe she wanted to bring peace? No one really knew the thought process, but everyone knew she was to become the Ambassador. ** This is a continuation of the Pacifist Route in Undertale. This contains ships, bits and pieces of the fandom, and other adjustments of which is my design.** **Please note, that I am an amateur writer with very little experience.** **None of the art is mine** **Undertale is rightfully owned by Toby Fox**

    How many times have you seen this world, how many resets does it take for you to give up hope? Does anything even matter after all this, does trying do anything? Will the struggle help at all, can I even believe in anyone anymore? The only thing keeping me going now is my resentment.

Having to live on the complete opposite side with poverty, she learns she has to hide, and everyone isn't what they seem. Not even her.

    Its been a year since the barrier has fallen and you're just an average girl going about your fairly normal day. A detour on your way home from work wouldn't hurt, right?
