Intro. You were born with a kind of curse or ability or whatever you may see it,that makes you change gender, when ever your feeling negative you are a boy,and when your feeling positive your a girl,your whole family knows this and gave you 2 names for the different genders of yourself,you kept yourself as a boy as you've been bullied in the past,now in highschool and nobody knows that you have this kind of thing that could happen to you
