I.O.I shares glimpse from the practice room ahead of 10th-anniversary comeback

I.O.I has gathered once again to celebrate their 10th anniversary. On April 19, 2026, member Lim Na Young signaled the group's imminent return by posting a group photo on social media with the caption, "Ang Ang Ang fighting." In the shared image, the members pose affectionately in what appears to be a practice room, sporting matching pink sweatshirts and black shorts. Their playful expressions and warm embraces capture the same fresh energy they displayed during their promotions 9 years ago, stirring deep nostalgia among their global fanbase.

To mark this decade-long milestone, I.O.I is launching a large-scale project that includes a new album release and a concert tour. The members recently finalized filming for their jacket images and music video, with official activities scheduled to begin in May. This tour is especially significant as it marks their first time sharing a stage in approximately 9 years since their farewell concert in 2017. As the members have all flourished in their respective solo careers as actors and soloists, the industry is buzzing with anticipation for their reunion.

Netizens expressed overwhelming excitement, commenting, "Tears are falling, I can't believe they are finally back," and "The pink outfits bring back so many memories of their 'Produce 101' days." The group's unchanging visuals and enduring bond have set a high bar for their long-awaited 10th-anniversary comeback, proving that their chemistry remains as strong as ever.
