His sole vow in life had been to shield her from harm, but he had failed catastrophically. The memory of her lifeless body, sprawled on the ground like a broken doll, still haunted him. The image of her pale skin, smeared with the crimson of her own blood, was forever seared into his mind. He couldn't bear the thought of it, the weight of his failure crushing him like a physical force.

He had possessed the power to save her, to snatch her from the jaws of fate, but now it was too late. The window of opportunity had slammed shut, leaving him with a gnawing sense of despair. He felt utterly useless, like a ship without anchor or rudder, lost in a stormy sea of emotions. Helplessness clawed at his insides, its razor-sharp talons tearing at his soul. Guilt suffocated him, a heavy chain wrapped around his heart, squeezing tight. A maelstrom of emotions swirled within him, a torrent of anguish, regret, and sorrow that he couldn't begin to articulate.

She didn't deserve to have her life brutally extinguished, for she was a radiant soul who embodied selflessness. Her heart beat with a generosity that inspired others, and her spirit shone with a light that illuminated the lives of those around her. She had a boundless dream to explore the world's wonders, to dance in the rainforests, to chase the aurora borealis, and to soak in the warmth of foreign sunsets. But fate had other plans, and her assailants ruthlessly snuffed out her flame, silencing her laughter, and shattering her aspirations. They took everything from her – her future, her promise, and her limitless potential – leaving behind only the echoes of what could have been.

Until now, the world had only glimpsed the depths of his compassion, the gentle touch of his empathy, and the soothing balm of his kindness. But beneath the surface, a storm was brewing. A spark of unyielding resolve had ignited within him, fueling a new vow that would shatter the very foundations of his existence. With a fierce determination burning in his eyes, he swore to unleash a maelstrom of destruction, to raze the world that had wronged him, and to leave nothing but ashes in his wake. The warmth of his empathy was about to give way to the fiery blaze of his wrath.

Life had torn his second from his grasp, leaving a gaping wound. He vowed to retaliate by stealing the joy from others, to dim the brightness that had been cruelly extinguished in his own life.

Little did he know that he will meet her, and she will change everything.
