She is nervous and is comforted by her friend Hyeon-su, whose parents are divorced, though she shares a good relationship with her mother Yoon-hee, a successful and talented plastic surgeon.

Hyeon-su, Jae-hui and Su-kyoung wait at a bus stop while an old woman hands out fliers for her missing granddaughter.

Jae-hui shows instant dislike for Sung-eon, who is tomboyish and hasn't undergone plastic surgery.

The girls attend Hyeon-su's birthday party and Su-kyoung gives her an expensive doll as a present.

Back in present day, Yoon-hee confronts her ex-husband and tells him that he has no right to see Hyeon-su.

Meanwhile, Jae-hui and Hye-won appear to become possessed in art class, cutting each other's faces with scalpels, uttering "I'll make you pretty."

In another flashback, it is shown that the real Hyeon-su, still with her face burned off, begins to show signs of improvement and Yoon-hee performs an operation.

Unfortunately Yoon-hee didn't fully keep her promise; she only made the girl very realistic masks of her daughter's face.

The Faceless Girl, now in her late teens, sneaks out of the basement and witnesses Hyeon-su's birthday party with all of the friends who would later have surgery.

Hyeon-su then discovers a fridge-like device which Yoon-hee kept the Faceless Girl's body in after her death.

Sung-eon sees who she believes to be Hyeon-su but it is actually the Faceless Girl who pulls her own face off like a mask.

Yoon-hee tells a panicking Hyeon-su that it is time to give her face back and begins to operate but stops when she remembers how much she loved her.

The title "Cinderella" is directed towards the orphaned girl, the black haired ghost in the story.

She can be dubbed Cinderella because she was illegally adopted after the original Hyeon-su suffered near-fatal burns and disfigurement from being in a car explosion.

The adopted daughter was never given any birthday parties, was never allowed to go to school, and was left inside the basement writing in her diary, hoping that one day her "mother" will make her a new face, as she promised but never did.

As she grew older, she felt more betrayed after watching Hyeon-su, the real daughter, grow up, becoming beautiful with her face and having birthday parties with her beautiful friends and thus ended up committing suicide in the basement, writing about how much she hates Hyeon-su, her friends and how she wishes she could kill them all.

Unfortunately, the mother finally decides to throw the orphaned girl a party and brings her a cake, only to discover that she had hung herself.

In South Korea and other parts of Asia, there is an extreme preoccupation with beauty and achieving it through plastic surgery.
