Missing girl

The next day Hyeon-su shows the picture of the missing girl from the old woman to Sung-eon and then shows her a photo given to her by her father. Sung-eon notices that they look very similar but have different eye colors. Meanwhile, Jae-hui and Hye-won are painting self-portraits. Hye-won goes to the toilet while Jae-hui washes her paint brush. She notices it gets stuck in the middle of the bucket of paint-water. As she inspects it a hand shoots out of the bucket and forcefully pulls her head into the bucket by grabbing her face. Jae-hui accidentally tears her picture. Sung-eon gets a call from Hyeon-su's mom. Hye-won returns and is shocked to see the painting ripped and scratches on Jae-hui's face, who now seems to be almost catatonic and in a trance-like state. Next we see the two girls sitting face to face and smiling in a possessed way as they draw lines on their faces, telling each other which parts of their faces need improving. They then lift up two scalpels and begin to slowly cut each other's faces up, both uttering "I'll make you pretty" at the same time, with their feet in the bucket. Hyeon-su and Sung-eon both enter the room to find both of the girls soaked in blood with shredded faces, smiling at the two of them. The ambulances come and the paramedics carry Jae-hui's and Hye-won's bodies away. Sung-eon is taken downtown to answer questions about the two girls.
