Seo Dan-Ah, the daughter of a pharmacist, has long been devoted to Kim Shin-Woo, the young master of a judge. When Shin-Woo falls ill, Dan-Ah visits his residence under the guise of procuring medicine, but upon arrival, she finds him possessed by a malevolent entity - a lustful spirit. The spirit demands that Dan-Ah satisfy its desires, threatening to release Shin-Woo only if she relents. Desperate to save her beloved, Dan-Ah agrees to the entity's terms, and a night of turmoil ensues. However, upon Shin-Woo's return the following day, he is transformed, exhibiting an altered speech pattern, personality, and even a change in his sexual orientation. The aftermath of this night leaves Dan-Ah perplexed and helpless, as Shin-Woo is now beset by three separate lustful spirits: a serpentine entity, a man consumed by obsessive desires, a devoted servant, and a submissive slave. Dan-Ah finds herself caught in a complex web of temptation, as each entity vies for control, threatening to destroy the relationship she holds dear. With her resolve tested and her emotions in turmoil, Dan-Ah must navigate this treacherous landscape to reclaim Shin-Woo and restore balance to their lives.
