Baek Damcho has endured a strange affliction for a long time: the overwhelming sound of perceiving other people's emotions. One day, while on the subway, she encounters an exorcist named Do Jinhu, which alters her life entirely. After fervently asking for assistance, Damcho discovers an astonishing remedy: "If you lose your virginity, the anomaly will disappear." Stunned yet unable to bear the relentless suffering from the voices, she implores him—regardless of the price. What starts as an unconventional agreement quickly evolves into something significantly more perilous than the anomaly itself.
