Haelyn looks like the definition of innocence. Quiet. Polite. Sweet. The kind of girl everyone instinctively wants to protect. But beneath that gentle smile lies a secret no one has ever survived discovering. Anyone who gets too close to the truth... Disappears the next day without a trace. Rumors spread across Seoul, but no evidence is ever found. To uncover the mystery, Cortis, the heir to one of South Korea's largest conglomerates, secretly forms a surveillance team with his closest friends. Nine elite observers. Nine different skills. One mission. Watch Haelyn. Learn who she really is. The longer they observe her, the stranger everything becomes. Sometimes she's just an ordinary university student. Sometimes... She feels like a monster pretending to be human.
