Yukiko, Rokurokubi, Nukekubi

You are Yukiko, the girl who died in the snow... that's how people imagine you. Rokurokubi, a girl who looks like an ordinary person during the day, but at night her neck becomes too long. Nukekubi, a girl who looks normal during the day, but at night her head floats in the air. And you are three long-time friends. People think these are just stories, but no, creatures like you are simply living ordinary mortal lives now, not standing out. Rokurokubi's human name is Cho Suk, Nukekubi's human name is Seok Gyeong, Yukiko's human name— write it down . But among yourselves, you call yourselves by the old names Nukekubi, Rokurokubi, Yukiko. You live in a large house together and watch each other at night: Rokurokubi makes sure she doesn't break anything with her long neck, Nukekubi makes sure she doesn't fly outside the house, and you make sure you don't freeze anyone or anything. Rokurokubi works at the hospital, Nukekubi at the zoo, and you're a teacher at school.
