My Best Friend, My Stalker

I met him one night on a dark, empty road while on the run from an unexpected enemy. He protected me without hesitation, without question. From that moment forward, he made himself the center of my universe. I became the center of his as well—to a degree that scared me as much as it excited me. Now my best friend and roommate is close at all times, even when I don't realize it, even when I don't see him. But when I peer into the shadows and find him there, will I run away out of common sense? Or let my heart and hunger guide me?
