2. Story Premise (Spoiler-Light Plot Summary)
Idol Eye begins when a famous idol gets pulled into a murder case and public opinion turns violent overnight. The story follows Maeng Sena, a criminal-defense lawyer who handles the cases everyone else avoids. Sena looks cold and unshakable in court, but Sena hides one very human weakness – Sena is a long-time superfan of the idol band Gold Boys.
When Gold Boys’ star Do Ra-ik becomes a suspect, Sena takes the case personally. Sena does not just fight to win a trial. Sena fights to expose what the spotlight tried to bury: secrets inside the agency, cracks inside the group, and motives that look completely different once the “perfect idol image” breaks.
