One and Only

I made a wish on my 18th birthday.
It was a wrong move.

"I wish I was exactly like Harry Styles, having such a perfect life."

Those were the last words before I blew out the candles.

Before I turned into him.

18 year old Jessy Harwood made wish on her birthday to be exactly like Harry Styles, seeing that he had such a perfect life. But instead, fate decided on other plans and made her BE him.

What happened to the real Harry Styles then?

He became HER.

What happens when they actually swapped bodies?
How would they cope, especially when they live in two totally different worlds?
And the most important question,
How would they be able to switch back?
