The theater and film student Jeong Ahyoung experiences an unsettling incident one day before the spring performance: her protective bracelet against bad luck breaks. After that, she begins to suffer from an unexplained fever, exhaustion, and nights when she can no longer control herself. Behind it all was an entity that feeds on human desire: a sex demon. To calm her strange symptoms, Ahyoung spends the night with her childhood friend, Kwon Seochan, and begins to rely on him. However, soon after, Kwon Yichan, Ahyoung’s first love and Seochan’s older brother, returns to university, creating a subtle rift in the relationship between the three of them. As emotions and confusion become intertwined, the influence of the sex demon grows deeper and deeper, eventually giving rise to an irreversible conflict between the brothers… Will the three of them be able to find their own answer beyond desire and the curse?
