Is it L.O.V.E. or love? (Frisk x Sans reader)

Frisk, a human teenager, bullied for hiding her eyes. One day, two of her bullys, Ryan and Sky, chased her to Mt. Ebott, resulting to her fall into the Underground, home of Monsters. Frisk had the power to reset the world, to when she fell, but in one of these resets, the most recent, the two bullys followed her.

Y/N, the pun loving, ketchup addicted, skelleton, yelled at by others, such as his brother, Papyrus, and head of the royal gaurd, Undyne, though he didn't really care. He hates making promises, but he has one that he's keeping, for the time being. He has the ability to remember the resets, which caused him to give up, knowing he'd never have a future.
