Following the release of the single album
Pit-a-Pat in November 2022, the group entered a 17-month hiatus from group musical releases; the longest since their debut in 2020. During this period, members Nana and
Wooyeon participated in the
Mnet reality competition series
Queendom Puzzle (2023), where Nana ultimately placed second and joined the project group
El7z Up. On April 1, 2024, SSQ Entertainment announced that the group had officially rebranded their name from "woo!ah!" to "Wooah" to signal a "new stage" in their career. Following the announcement, "Blush" was revealed as the group's first release under the new name and the comeback scheduler was announced on April 2, 2024. The song was released digitally on April 8, 2024, along with its accompanying music video. It was later included as the fourth track on the group's second
extended play,
Unframed, which was later released on June 17, 2024. == Composition ==
