Brighter than the Stars. (Undertale: Papyton. Human!Au)

Mettaton is rich, lives in a mansion, and is an international superstar. But deep down, he needs a friend. He transfers schools to a place called Snowdin where he meets new friends and reunites with his cousin Napstablook.

Papyrus is a hard working boy of the town of Snowdin, also a sudent at the local school. When a new boy - his favourite celebrity - transfers to the school, and starts hanging around the town he can't seem to get the well known star out of his head. But his nerves get the better of him, and can't seem to muster the courage to talk to Mettaton.
