Since childhood, Sooha has been trained to conceal her extraordinary abilities to avoid being labeled a vampire. After an incident where she was unjustly blamed for her childhood friend's death due to those suspicions, Sooha enrolls at Decelis Academy, a night school believed to be off-limits to supernatural beings like vampires and werewolves.
Upon arriving at the academy, Sooha meets Heli, a student who remains her friend even after learning her secret. Heli then introduces Sooha to his close-knit circle of friends: Jaan, Jino, Shion, Jakah, Noa, and Solon, each possessing unique powers. Their connection to Sooha goes beyond simple friendship, as they seem drawn to her and willing to fulfill any request she makes.
A recent murder linked to a vampire reveals the dark past of Heli and his companions. Despite their attempts to protect Sooha from the supernatural conflicts, she finds herself increasingly entangled in the ancient feud between vampires and werewolves. As the situation escalates, Sooha discovers she may have a closer connection to the very creatures she fears most.
