It is a sick craving she has for him.
It's love, even though she fights against it.
He is like a perfect picture, with raven colored hair and blood red eyes not to mention his tall and slender, yet muscular body. She has heard countless other girls whisper and gossip about how marvelous he is, how perfect he seems. She always snorts inwardly, because she knows that he is so far from perfect, it's almost terrifying.
She throws herself at him all the time, knowing, or maybe hoping, that it'll push him away from her. He stares at her with such distaste, she believes that it's worked. She believes that he only sees her as an annoying fan girl whom he is always just on the edge of discarding.
It isn't until she is accidentally separated from the group does it become apparent that she not only craves him, but loves him. She knows that once she calls out Sasuke name instead of continuing on her way. It is then that she realizes that not only does she lust after him, but that she cares for him. She knows she should be happy that she can flee the team, flee the ever constant fear of being shot down where she stands.
But she isn't.
And so, instead of running away from her current spot, she remains. She sinks to her knees. She allows a bitter sob to shake her body. And she sits there for many days, many nights. She slowly starves and only drinks the rain water that leaks into her mouth, which keeps her alive much to her despair.
When she hears the leaves that lie on the forest floor crunch beneath someone's weight, she breathes out words of relief. Just not the one the person was expecting to hear. "…end it all, please…"
She shuts her half lidded eyes, expecting to never see the light again. Yet when her heart continues to beat, she allows her eyes to open ever so slightly, just as a rough, large hand brushes away the dirty, mud matted strands of hair away from her face. She knows who's hand that is, and her heart stop. She feels herself being hoisted up, off the ground and into someone's arms.
All of the sudden she doesn't feel so wrong to love him. All of the sudden he seems much more human, and less terrifying.
It is as if he is reading her thoughts when he says words that seem misplaced in his mouth. Because even though they are cold, they hide some sort of hidden meaning and emotion. "Get yourself lot again and I'll kill you."
And the sick craving is no longer so sick and the love is no longer so brutal.
