*Hello dear fans of undertale and its universes!
Welcome to my book, where the term "y/n" was originally a different character! This story started way different from before in drawings that I made with totally different concepts and characters. The only thing that stayed was the fact that people got isekai-d into an undertale multiverse thingy, and that there is a surprise change of character. Everything else stayed or I never even made them up on paper. I hope you will like it either way!

Having said that, let's hop onto this chapter!*

And as every one of the big-eyed skeletons looked at me, I managed to mutter which one of the sans' I will choose as my only

I almost got it out of my mouth when suddenly...

„SIS!" My thoughts were suddenly interrupted by my little brother, (ch/b/n(the made-up characters little brother's name))

I was about to run to my little brother when suddenly G grabbed my hand.

„And? You won't tell us who you will choose?" He said with a pleading look. „Even after all, we went through (you)?"

I just sweetly looked at them, making every one of the guys blush because of it. I pulled my hand out of his grasp running towards my brother.

This was it.

Now I can say I'm truly happy.

With everyone that I truly love.

My (youreyecolor) orbs were filled with tears as I smiled brightly at my little brother.

Nothing will be able to change it now.

(Y/N)'s POV

I pause a little.

There is something in me that it's not sure if this would make my followers happy or not. After all... A cliffhanger ending like this is pretty common in some of the books I read. But...I also read isekaid stories where that was the reason why the main character got angry and made them say what they would have changed in it.

„...And? Aren't you gonna post it?" My friend, (fr/n=friends name) checked my writing through the VC they and I created just for this work only.

Their voice sounded tired, which was not surprising since it was in the middle of the night. I felt grateful that they managed to stay up so late just to help me, but I was also aware of how their working schedule is, so I needed to finish the chapter as fast as possible. Still, I was not convinced of the ending that I made for it.

„I'm not sure. What if nobody likes it?? What if I make my followers upset by the thing I wrote?" I nervously asked them, not noticing the resting bitch face that they gave me.

„If that was it, don't you think they would have already said something in regards? It was noticeable the outcome either way." They said, not giving it time to think about it, them being so tired and all of that.

"Yeah but..." I started.

"Bestie." (fr/n) said sternly interrupting my speech. "Everything is completely fine, ok? The people will like it. Let's just go to sleep now. Everything would be better with a fresh mind anyway." They continued as a yawn escaped from their lips.

I tried to say any other contradictions, but nothing came out. "...True. You should go to sleep, I still need to check things around my writing anyway." A smiled at them saying goodnight to them, before closing the voice chat.

I looked around a little bit seeing my quite messy room. Shirts and other clothes were all over my bed.

I should probably clean that up... Well, maybe tomorrow I will do it.

Aside from my clothes which should have been put in a totally different place than my bed, there was stuff that was really precious to me. Like an old photo of me and (fr/n) that we took on our first hang-out after the quarantine. It was a really nice time, us at a cafe talking about all the stuff that we started. Like my fanfiction, which was the same time that I dragged them into it.

But maybe I should have started off with an introduction. (y/n) [if you have one then (md/n)] (l/n), an Undertale and it's aus enthusiast. Made a fanfiction where I probably followed some of the fanon personalities of all of the skeletons, but I started off this story as an amateur, so please accept my deepest apologies over how I wrote stuff in it.

But anyway, looking around I took a deep breath and turned back to my work. I still wasn't really sure whether or not it is good enough for my readers, but I just post it as it was, hoping that they would like it.

Right after posting it, I closed off my laptop and went straight to bed. In front of it were posters made from my favorite artists that made stuff related to Undertale or it's alternate universes. On my bed there was a plush of Toriel which it may suprise some of the fans, since I also made a fanfiction about the skeleton boys, but hear me out. That goat just warmed up to me with their cooking and the fact that they tried to make the player as comfortable in their place as possible.

...Anyway, as I was saying, I went straight to bed. Starring at the ceiling I thought about many of the possibilities that I should have went instead of this kind of ending. After all, even if writing stuff on Wattpad wasn't something that may affect my life, it was still something in which I felt improvements on my writing skills. As I was laying in bed with those thoughts filling my mind, I slowly drifted into a deep slumber.

-*-

I woke up to an annoying, yet familiar ringtone, that my dear friend (fr/n) put for themselves. Still with a tired face I answered to the call from them, only to be met with their yelling.

"(Y/N) JUST HOW MUCH DID YOU CHANGED ABOUT THE FANFICTION?!?" They managed to make their yelling sound as suprised as possible through the mic of their phone. I, still pretty much half-asleep was confused over their statement. I wasn't even able to touch the rest of the fanfiction after posting the chapter which I made with them.

"...I didn't. After we talked I soon published the chapter, and went straight to bed... What are you even talking about?" I asked them with confusion plastered on my tired voice.

"THEN HOW CAN YOU EXPLAIN THAT FUCKING BAD ENDING?!?" They said, which made me instantly woke up. I didn't made the story into a bad ending one.

"Say that again!" I asked as I jolted out of the bed rushing towards my laptop.

"Didn't you hear me before?!? Your fiction got hugely changed!!!" They stated as I watched in horror the comments about the sudden change. I quickly went to see the whole story.

"...What the-"
