The Chosen For Black Butler(Black Butler x Modern Male reader)

There was once a boy named (y/n) (l/n) who thought he made a big mistake however. once he put on that necklace, everything changed for the better. In his original world, he just lived in an apartment and had a job as a programer and artist, his parents would still give him money each week. One day, some one grabbed him and pulled him through the TV screen. But he did not know he would be exactly what they were looking for to watch over the world and it's timeline. And how could this all happen to a boy that is only 17 and with a necklace, maybe because he was never really human in the first place...
