My first first love

She was dry Ice, iginated when tried to calm down,
He was ice, numbing the people out of his way,
She was feisty,feirce,hot.
He was calm, cool, smart.

But these personality's were developed after being splitted Apart,what was their past? And what made them like this? And why on the earth did destiny played this game to unite them in such different and awkward circumstances?

Imagine a bunch of boys in your "only girls"school and one of them was your longterm crush and bestfriend.
