United as One (ONE TREE HILL//OCxOC)

Calista Scott is invisible when it comes to her family. Her mother is barely even home, her father is too laser-focused on her ignorant twin brother to even notice her successes, and her older half-brother detests her existence. Even though she doesn't know it, but the only person that can see her outside of being the sister of Nathan Scott is the best friend of Nathan, and soon, she would begin to believe it.
