Yoon-hee tells Hyeon-su it's time to give her face back and begins to operate with a scalpel but stops when she remembers how much she loved her. Yoon-hee collapses to the floor in grief but the corpse of the faceless girl gets up and tries to cut off Hyeon-su's face screaming "I want my face back!". Yoon-hee stops her, telling her that she's her precious daughter and that she's sorry for all she did to her. The ghastly faceless corpse reverts into the child she once was. The Faceless Girl was The Orphaned Girl all along, not the real Hyeon-su, and the operation had been a face swap. Yoon-hee had cut off the Orphaned Girl's face and had given it to Hyeon-su. Yoon-hee then repents for her sins and leaves with the Orphaned Girl to go onto the Afterlife. However, the final scene shows the Orphaned Girl, back in her faceless long-haired form suddenly appearing by Hyeon-su's bed with her hands reaching out before the credits roll, perhaps meaning that she was not yet satisfied and still wanting her face back.
