Adopted Assassin

(With AC) The day you were born you were sold off to a secret organization that trains assassins. You were sent out to do your first mission. It was a success, but you bumped into a kid that looks just like you at an orphanage. The two of you got to talking and after playing together you passed out on the grounds of the orphanage. The organization swooped them up instead of you and now you are about to be adopted instead of them.
