Genre: Psychological thriller • Mystery • Drama • BTS AU Chapters: 21 (Complete Series Plan) Tone: Dark • Cinematic • Symbolic Synopsis: When a haunting melody resurfaces in Daegu, it reopens the wounds of a forgotten experiment. A detective haunted by guilt. A journalist chasing silence. A composer obsessed with control. A painter who sees sound. A lawyer connecting patterns. A boy who remembers nothing. A leader trying to hold the truth together. A city that listens when it should not. Seven men-each tied by the same frequency. Years ago, Project ECLIPSE aimed to study the connection between emotion and sound. But when its lead researcher, Min Yoongi, vanished, the project was buried under layers of secrecy. Now, as strange disappearances plague Daegu, fragments of the past return-each note revealing another lie. Every melody hides a message. Every silence hides a scream. And the line between music and madness begins to fade.
