When you'd first met Lucas, you had saved him from getting shot. Gratitude had turned into emotional attachment, and soon, despite knowing that he belonged to the dark side of the world, you had come to love, and be with him.
But that was until he started questioning you - questioning your name, your identity - and why you had saved him. He searched for ulterior motives behind your actions, not caring that the rift between you was widening. Initially, you'd fought him, fought for your love, fought for your feelings, fought for him. But then one day, he had cocked a gun to your forehead, and said that you were unable to trust, and unable to love.
That was the breaking point, and now, five months later, you're back to your old life, ignoring calls and texts from him after you'd come to know that someone had filled his ears. But you don't care, because you're done - you don't know any Lucas Cox anymore.
