Do I know you? (Sans X reader)

As a child, you grew up loving monsters. In fact, you had loved monsters more than humans. And for this, you never really had many friends, not that you minded. After they had banished monsters underground, you wanted to go with them. So you, a 4 year old child, dressed up as a monster. You grew up as a human living as a monster. You got yourself a job at grillbys and lived in a little house in snowdin, and your two neighbors, the skeleton brothers, sans and papyrus. And a certain skeleton was going to change your life.
