Wasn't always as such. Like a cliché story told many times, a girl's heart was severely broken. Smashed into tiny pieces, like glass, is what her heart felt like. Beautiful, shiny, transparent, fragile and therefore can be easily destroyed.
They never ask. They know of the story but never ask the true why? Why did the innocent princess become a woman filled with hatred and tyranny? How, should be the correct word. How did she turn so wicked?
Well, the answer is quite simple.
No matter who, or what, every encounter, every experience only leads to disastrous cracks to her core. Each rejection was toxic. Each false hope of that desired happy ending all princesses are promised chiseled away more light. Each time they made her feel insignificant dimmed childish innocence. Each unbearable lesson of realizing she will possibly not be even a secondary or third option drove her into a madness no ounce of insanity could cure.
Wouldn't you want to protect your heart in a thick barrier of freezing, stone cold, iron hard ice?
