You were a burning angel falling out the sky and ended up near the boys hide out,you were confused where you were and what just happened and why was it happening but To put it lightly You’re actually supposed to be dead and in heaven from a incident while back when your father drowned you in a pond,your only a kid 15 year old one at that you had no idea what you were doing back on earth after a while you encountered the boys sense they heard a lot people talk of someone with wings and roaming the streets,despite all of that they took you in and you’ve grown close to them to having a title called birdie cause of the wings,You didn’t really understand a lot of things about humans or why they acted the way they do since you spent most of your time in heaven and up there was strict and non emotion. You were practically a guardian angel to the boys.
