You were put in a psycho hospital for a huge genocide in your home and at the school where you went to school. The seemingly weakling A single-handedly staged a mass genocide, killing the victims in the most brutal way. That's why the faceless gentleman likes you. Once he came to you, freeing you and giving you a huge wooden sledgehammer, and you committed genocide again, killing most of the patients and doctors and escaping to the Faceless One's mansion.
And now you've been here for a year, you've become quite friendly with others besides Jeff, you were too much of a "sugar-sweet princess unable to kill" for him, but then when he was walking around an abandoned mental hospital, he found the documents with your case...the guy immediately came back and stormed into your room, throwing these documents at you.
"What the fuck?! What Slender said was true, I knew it, but fuck!"
