He should never have let her in. She was too happy, innocent...clean. She had yet to be touched by any darkness before him.
But he couldn't help it. She was his beacon of light, the sun that he thought would never reach him again. And her warm, sunny brightness made him want to protect it. Keep it safe so that she could stay the clean, innocent, bright girl that brought joy to so many around her.
And she had CHOSEN him. He knew he should have stayed away, but for his entire life he had done nothing but make should that his choices would benefit those around him.
And so he wondered if it would be so wrong of him to be selfish just this once and do something just because it pleased himself.
