Wohn Ku is a vampire that needs human blood to survive. As a tenderhearted child, she led a tortured existence until a girl named Seyeon willingly became her steady blood source. Seyeon stood by Wohn throughout their school years, defending her from bullies. Fast forward to the present where they move in together ahead of their freshman year of college. Seyeon remains fiercely protective of her friend, but Wohn is ready for a fresh start. When a devoutly religious sophomore girl named Juyi showers her with kindness, Wohn emerges from her shell only to realize that Juyi had once been her father’s kidnapping victim, a potential blood source she had refused to bite. Juyi grows closer to Wohn without remembering the incident, fueling jealousy in Seyeon. Will Juyi prove to be a savior washing away Wohn’s guilt, or will she ruin a vampire’s dream of redemption?
