The one who couldn't love

Prologue

I'm a murderer..

I killed the girl that i used to be..
The girl that used to smile and care all the time..
The girl that used to have a lot of friends
The charming little princess who loves everybody.

But she's dead.
I killed her with pain..
Her eyes now are a darker color
She rarely smiles
She's reckless and cold.
She's not a princess who needs savior, she's a queen that has to fight for herself from pain..

And she's the dangerous girl your mother warned you about.

Is she the one who couldn't love?
