Hyeon-su then discovers the girl's room and explores finding a cupboard filled with the masks she wore over the years and a diary filled with sadness and hate towards Hyeon-su and her friends. Hyeon-su then discovers a fridge-like device which Yoon-hee kept the Faceless Girl's body in after her death. Sung-eon, now free of the police visits Hyeon-su's house and breaks in, unlocking the basement door and the two separate to search for Yoon-hee. Sung-eon then sees what she believes to be Hyeon-su but it is actually the Faceless Girl who shocks Sung-eon to fainting by pulling her own face off like a mask. Hyeon-su finds the unconscious Sung-eon; her mother then appears and drugs her.
Hyeon-su lies on an operating table next to the corpse of the Faceless Girl, who is wearing a mask that resembles Hyeon-su's face. Yoon-hee removes the mask, revealing the faceless girl's gruesome visage properly for the first time. Hyeon-su begins to panic, but she can't move because of the drugs.
