He’s been alone as long as he remembers and the only thing that could be a “clue” to his identity and hidden memories is a metal plate drilled into his right hand.
Or Gaster tries to find answers but everything goes worse for him.

Where Do Monster Souls Go When They Die? by Just_AliAnne261
Fandoms: Undertale (Video Game)

Summary
"Papyrus felt... strange. Softer. Lighter than ever before.
He could've sworn he was just in his bedroom a minute ago. He remembered his old, cold bones curled up under the sheets, his soul crying out with deep, painful loneliness. He's pretty sure he just fell asleep in that bed with tears running down his face.
He's never been the same since Sans passed away two years ago.
But now he's on a fluffy white cloud, high in the sky. At least, that's where he thinks he is."

Sometimes Frisk has to wonder, how on earth did Sans and Papyrus manage to live on their own as long as they did?
After the monsters were set free, Toriel, the skeleton brothers and Frisk all moved in together, creating their own little makeshift family. However, with great family comes great stupidity. At least, that's how Frisk would describe it.

(I will not finish this. Check my rewrite in my account) The scientist W.D. Gaster has always been alone for as long as he could remember. He tries to find out what happened to his lost memory to no avail. Maybe it’s nothing, but… then why did his parents leave him? Especially with this weird plate stuck to his hand, what’s up with that?
Or Gaster loses memory, why is that? And what’s with that metal plate??
Handplates AU but reversed.

Most people can drown out background noise with ease. They might not even notice it until someone points it out.
