Because of the things Yeong Hye has bore witness to, the things she's been made to endure at the hands of other human beings, she finds humanity to be an inherently violent thing. She cannot exist as a human without hurting something. She hates her teeth, they are meant to bite and tear away at the flesh of other creatures. She hates her nails, they are meant to scratch and hurt and draw blood. She continues to lose weight as she refuses to eat meat. Her edges are all sharpening, she says. She doesn't understand why, if she is trying so hard not to hurt things, to make herself entirely harmless and soft, why do her edges only sharpen? Because she is human, and sharp edges and harm are what she is meant for. So she simply will not be human.
