Synopsis: Fill Me With Your Lust!

One day, just prior to the spring performance, Jung Ah-young, a student of theater and film, encounters a troubling event when her protective charm breaks. Following this, she suffers from unexplained fevers, fatigue, and nights where she loses control of herself. Behind all this is a "lust demon," a parasitic being that feeds on human desire! In an effort to ease her peculiar symptoms, Ah-young spends a night with her childhood friend, Kwon Seo-chan, and starts to depend on him. However, shortly thereafter, Kwon Yi-chan—Ah-young's first love and Seo-chan's older brother—returns to school, creating a subtle tension in the dynamic between the three. Amid a web of emotions and confusion, the grip of the lust demon intensifies, ultimately leading to an unavoidable conflict between the brothers… Will these three manage to rise above desire and the curse to discover their own resolution?
