Hey, Doll | Gaster!Sans x Reader

Alone in a condemned world where monsters and humans fight for power constantly, Y/N survives off of the wood's riches and the small scraps of shelter she can find in ghost towns. Allies and friends have come and gone during the war, either killed or have parted ways. It's not all that bad. She could be dead, after all.

One afternoon when shipments from the Human Capital come on a train, she meets a mysterious stranger who saves her life. He's a monster, no doubt, a skeleton to be exact.

Y/N is intrigued by the monster and decides to follow him into the next town over where he disappears into an abandoned warehouse. Y/N follows him in only to be pinned to the wall for questioning.

After answering all his questions, introductions are made and Y/N learns that the skeleton's name is G. Y/N likes G despite his hateful nature and somehow convinces him to let her come along on a quest he's taking to save his brother from the Monster Capital where they took him for war.

After surviving assaults, the government, and Mother Nature herself, Y/N and G start to form a special bond that neither of them wants to break.

But when everything goes wrong and neither of them is strong enough to prevent it, Y/N finds that the capitals that she had always hated are far more sinister than she could've ever imagined.
