The boy who became a girl

I was a former gang member, but when I entered high school I got serious.

My grades aren\'t good, but my behaviour is adequate. I have 0 friends because of my face and a rumour.

One day, I received a rare energy drink from my younger sister, so I drank it at school.

As I was chilling on the roof, a fireball hit me from above my head.

Then, my body changed, my chest swelled up, and my butt became big. My waist became thinner, my shoulder width got narrower and my hair grew. Also my height shrank?

This looks like a girl… does it not?

How did this happen…
