Cheonyeo Gwisin

The cheonyeo gwisin appears in a white mourning robe, long black hair hanging over a bloodless face, haunting wells, old trees, and empty houses. In Joseon thinking, a woman who died unmarried had no husband's line to enshrine her and no descendants to feed her spirit, so she could not join the ancestors and lingered in the world; if she had died wronged, the grievance bound her tighter. Folk remedies included posthumous ghost marriages and the ssitgim-gut, a shamanic rite that unties, knot by knot, the resentments holding a soul back.

The most famous of these ghosts is Arang of Miryang. A magistrate's daughter lured out by her nurse to view the moon by the Yeongnamnu pavilion, she was assaulted by a yamen servant, killed for resisting, and dumped in a bamboo grove. Every newly appointed magistrate was found dead of fright after his first night, and Miryang became a posting no one dared accept, until one official sat up with a candle and heard her story to the end. At the next morning's assembly the ghost identified the culprit, in some tellings as a white butterfly alighting on his hat. Her bones were recovered and buried, and the Arang-gak shrine still stands below the pavilion. The late Joseon novel Janghwa Hongnyeon jeon tells the same pattern: two sisters drowned through their stepmother's plot appear nightly at the magistrate's office until an official finally asks who they are.

The skeleton of these stories is a delayed hearing: the ghost returns again and again because no one has yet listened to the end. In the twentieth century she moved into schools, and the white-clad girl of the toilet stall and the night study hall became the stock figure of Korean campus horror, carried into East Asian cinema by Whispering Corridors (1998) and A Tale of Two Sisters (2003).
