The demon's heir

Who was she?
She was the embodiment of enticing temptation. A mistress of vile nature. A true child of deception. A vessel of possession, manipulation and seductive vice.
A dangerous beauty.
A true child of the devil. A demon.

Then she met him, and she knew she smelt wrong.
He couldn't possibly be her soulmate, could he?.
Enemies could never be one, there was no way, she was dark, and he was light.
It could never work, not with the upcoming battle between both races.

She had a choice to make; Her origin and family, or her fated soulmate?.
It's obvious who she'll choose... isn't it?.
Or Will thumping heart affect her choice?.
