Reject! Sans x Reader {An Undertale Fan-fic}

You live on the surface. You were born half human and half monster. The monster half of you is actually a skeleton. You were abandoned by your parents when you were born and put in an orphanage. At the age of 8 you were then abandoned by the orphanage and left to fend for yourself because you had hurt some of the other kids with your magic since you haven't learnt how to control it, and being half human half monster scared most of them. You are known as the Reject and are picked on by everyone that's sees you and sometimes you choose to fight them. You are now 19 and the monsters have been freed. Things might get interesting.
I own nothing but the story!!
