The fact that the members participated in the songwriting adds weight to the album's finish. Along with the release, I.O.I announced the 2026 I.O.I Concert Tour: LOOP. The show, held at Jamsil Indoor Stadium in Seoul from the 29th to the 31st, is expected to be a stage to commemorate the group's 10th debut anniversary and the release of a new album after about nine years.
