In Korean culture, deeply influenced by Confucianism, fulfilling social and family duties is essential. Traditionally, a woman's primary duty was to marry and have children to continue her husband's lineage. Dying before fulfilling this destiny was a tragedy that generated immense 'Han', a Korean concept of resentment, pain, and accumulated sadness. From this Han, the Cheonyeo Gwishin, the ghost of the virgin, is born.

The Cheonyeo Gwishin is the most recognizable archetype of a Korean ghost: a young woman with long, black, loose hair (symbolizing her unmarried state, as married women wore their hair tied up), dressed in the traditional white mourning attire, 'sobok'. Her appearance is pale and sad, sometimes with blood in her mouth. She wanders the world of the living, unable to cross over to the afterlife due to her incomplete life.

Unlike Western monsters that attack randomly, the Cheonyeo Gwishin usually haunts her family, bringing bad luck or illness, or appears in villages causing droughts and misfortunes until a 'boda de almas' (a shamanic ritual where she is posthumously married to the spirit of a single man, a 'Mongdal Gwishin', to calm her resentment) is performed. Her legend is not just a horror story, but a social critique and a reflection of the immense pressure women suffered in Korean patriarchal society. Her terror does not come from malice, but from the infinite sorrow of a life not lived.
