A Classic Nightmare

Description:
Classic finds himself in what he thinks is an AU. After fending some bullies away from a cute purple skeleton, classic comes back more and more, getting closer to nightmare. One day, classic arrives to find the AU desolate, with nightmare nowhere to be found.
Years later, the Star Sanses begin a quest to find the original sans... but of course Nightmare has been looking for classic the whole time.
Who will find him first? Will classic still recognize nightmare?

It has a slow start, but it gets juicy pretty quickly. Lots of fluff, some angst, and a little bit of yandere nightmare!

Yes. I know. It's a weird ship, but I just had an amazing story idea that I started obsessively planning out and I just needed to write it down. I don't really expect anyone to read this, but it's a good story, I promise.

I do not own the characters, only the plot of this story.
