The Cheonyeo-gwisin arises where Joseon-era marriage norms met shamanic belief. In an age that treated marriage as the social completion of a person, a woman who died before achieving it was believed to become a vengeful ghost carrying unresolved han — grief — lingering near the living.
She is pictured in white mourning clothes with her hair undone, and is also called Songaksi. The horror lies not in violence but in unfulfilled longing: han itself, given form and set wandering.
