Hyeon-ju had dark eyes and long brown hair, which she wears loose with a small side fringe. She wore the standard Hyosan female uniform as well as sweatpants under her skirt. She wore the Hyosan High School grey hoodie when she was bullying Jin-su on a rooftop in Episode 1. As a zombie, her face is bloody and pale, with veins popping, and she's missing her shoes.

Little is known about her other than the fact that she was a bully, and the other students didn't wake her up for fear of her.
