In a kingdom divided between light and darkness, Prince Jeongin is sent to Blackthorn Castle. But the castle is ruled by Bang Chan, an powerful vampire-demon lord feared by everyone who knows his name. Cold, possessive, and terrifyingly obsessed, Chan becomes fixated on Jeongin the moment he arrives. Trapped inside a castle, Jeongin must learn how to survive among deadly vampires, demons, and creatures who seem far too interested in him. But Blackthorn hides more than secrets within its walls - it hides tension, desire, and dangerous loyalties. As obsession turns into something deeper and far more destructive, Jeongin begins to realize the greatest danger inside Blackthorn Castle may not be the monsters surrounding him- -but the fact that part of him wants to stay. *Ships : • Jeongchan • Minsung • Hyunlix • Seungbin
