IZ*ONE’s third mini‑album, "Oneiric Diary," fuses the group’s elegant charisma with everyday girl imagery, creating a concept where ordinary diaries transform into magical, fairy‑tale‑like stories. The title track, "환상동화 (Secret Story of the Swan)," is a cinematic EDM dance song that portrays the members as protagonists of a dream that becomes reality, encouraging listeners to become their own fairy‑tale heroes.
