During his school days, Gio accidentally discovered a rock band called Aurora, which became his muse. Inspired by them, he pursued a career in music and became a skilled composer. However, Aurora couldn’t survive in the overwhelming digital music market and eventually disappeared. Gio could never forget the voice of Aurora’s vocalist—until one day, a mysterious man named Seon-Gyu appeared before him. Their first encounter was suspicious, but through his best friend Hee-Seop, Gio learned an astonishing fact: Seon-Gyu’s voice resembled that of Aurora’s vocalist.
