Prologue: Meeting her

Good or evil. Life or death. Light or dark. Living or dying. None of those mattered to (y/n). For as long as he could remember he never really felt anything for anyone. No love, hate, envy, pity, nothing he didn't even feel sadness or grief for his parent's deaths. Eventually everyone avoided him. All the other children at the orphanage began calling him a freak, a psycho, empty, and a grimm. None of that bothered him in the slightest...at least not until he met her. The one woman who finally let him feel things, he finally felt all the emotions that he had never felt before, but will his new life show him true happiness, or will it lead him down the path of darkness into a living hell?
