She was the best thing that came into his life.
The quality of her positive influence did not penetrate into the mind of the man who robbed her of her innocence and dimmed the light in her eyes.
She predicted he would sabotage her existence yet; her fascination with hearing sweet nothings manifested too well leading to her blindness for failure.
When she finally realized that her good deeds were all for nothing, she would only have enough courage to steer away from him.
When she is gone, only then he will realize that the only thing that kept him grounded is now just a great loss engraved in his memory.
