What Does “HEYA” Mean?

'HEYA (해야)' — a wordplay on the Korean word "해야" meaning "must do" / "have to" — is an assertive declaration of intent, describing a feeling so overwhelming that acting on it is inevitable. The song uses a commanding, hip-hop-influenced production to frame IVE's bold energy, and the fantasy-themed MV launched a new mythological concept arc for the group.
