Naruto: The Outsider's Resolve - Chapter 4.8 (108):

Zara Hansley had always believed herself forsaken by the gods due to the terminal illness she was diagnosed with. Every doctor she visited had declared she would not live past her 23rd birthday.Yet, when left with only a few months to live, Zara found out that the root of her illness was a curse, one which she could break. Just like that, she was given a new chance at life—she had to scour the earth for the cure in just a few short months or succumb to her fate.Fate, however, was a funny thing—it brought her to a stranger that would alter the course of her life forever, and his life by her.Born to an ancient family, Amir Frostcrown was cursed to bring misfortune to any female around him. Not only that, he was able to hear the thoughts of others, thus further drawing a line between him and other ordinary folk. As such, while these abilities amassed him an enormous wealth over the years, he was destined to live a loveless life of solitude.That all changed when his and Zara’s paths crossed. As someone that was completely unaffected by his curses and abilities, Amir Frostcrown was immediately intrigued by this dying girl.One dream, one vow, and two curses. That was all it took for Zara to tumble from the world of reality into fantasy. Would she be able to find her cure in time? When secrets are revealed, would Zara and Amir Frostcrown stand the test of time?***“We were fated to be from the beginning!” he amusedly declared as he looked at her dotingly, eyes sparkling and only her image visible in his blue eyes.“I don’t believe in fate!” Zara mumbled softly as she looked to the ground, afraid of facing him and the undeniable truth he spoke of.“But don’t you see?” Amir asked. “Isn’t fate what led us to this very moment?”
