The K-Pop industry is buzzing with excitement as one of its most legendary project groups prepares for a historic return. After nearly a decade since their farewell concert, the “Nation’s Girl Group” I.O.I has officially confirmed their highly anticipated reunion. Set to celebrate their 10th debut anniversary, the group will release their third mini-album, I.O.I : LOOP, on May 19, 2026. This monumental comeback marks a significant moment in K-Pop history, bringing together nine of the original eleven members for a new era of music and performances.
A Historic Reunion After Nine Years
Formed in 2016 through the inaugural season of Mnet’s survival show Produce 101, I.O.I quickly skyrocketed to fame. They captured the hearts of millions with hit tracks like “Pick Me,” “Very Very Very,” and “Whatta Man (Good Man).” Despite their immense popularity, the group’s original contract was limited to just nine months, leading to a bittersweet disbandment following their final concert in January 2017. Since then, the members have pursued successful solo careers and joined other prominent girl groups, but fans have always held out hope for a reunion.
That hope became a reality when Swing Entertainment officially announced the comeback. The agency confirmed that nine members—Lim Na-young, Chungha, Kim Se-jeong, Jung Chae-yeon, Kim So-hye, Yoo Yeon-jung, Choi Yoo-jung, Kim Do-yeon, and Jeon Somi—will participate in the upcoming promotions. Unfortunately, Kang Mi-na and Zhou Jieqiong will not be joining this time due to prior commitments, with Kang Mi-na currently focusing on her acting career. Nevertheless, the return of the nine members has sent shockwaves through the K-Pop community.
“I.O.I will make their comeback on May 19 by releasing their third mini-album ‘I.O.I : LOOP’.”

Unveiling the ‘I.O.I : LOOP’ Promotion Schedule
The excitement began building when a mysterious Instagram account, @ioi_10th, surfaced in early March 2026. Fans quickly connected the dots, and the account soon became the central hub for all comeback updates. The promotional rollout for I.O.I : LOOP is packed with content designed to keep fans engaged leading up to the release.
The schedule kicked off with a captivating mood film released on April 22. The video features the members in colorful, vintage-inspired outfits, showcasing their individual charms while hinting at the album’s concept. The phrase “It never ends” appears in the teasers, perfectly aligning with the “LOOP” title and symbolizing the group’s enduring connection with their fans. Following the mood film, concept photos and a tracklist will be unveiled, culminating in a pre-release digital single on May 4, which coincides with their actual debut anniversary.
On the day of the pre-release, the group will also host a special 10th Anniversary YouTube Live broadcast, allowing them to interact directly with fans from around the world. This interactive event is expected to be an emotional milestone, bridging the nine-year gap since their last official group activity.
The ‘LOOP’ Concert Tour: Taking the Stage Across Asia
In addition to the new music, I.O.I is preparing to meet their international fanbase through the “2026 I.O.I Concert Tour: LOOP.” This tour represents a massive undertaking and highlights the global demand that still exists for the group. The concert series will kick off with a three-day residency at the Jamsil Indoor Stadium in Seoul from May 29 to May 31.
Following the Seoul performances, the group will travel to Bangkok for a show at Idea Live, Bravo BKK on June 6. The tour will then head to Hong Kong for two nights at the Asia World-Expo, Hall 10, on June 20 and 21. These concerts will not only feature live performances of their new tracks from I.O.I : LOOP but will undoubtedly include nostalgic renditions of the classic hits that defined their debut era.
The announcement of the tour has sparked a frenzy among fans, many of whom have waited nearly a decade for the chance to see I.O.I perform live once again. The concerts are expected to be highly emotional events, celebrating the journey of both the artists and their dedicated supporters.
A New Identity for the Fans: Introducing ‘Angdungi’
One of the most touching aspects of this comeback is the official naming of I.O.I’s fandom. For years, supporters of the group existed without an official title, united simply by their love for the eleven members. Now, in celebration of their 10th anniversary, the group has officially dubbed their fan club “Angdungi” (앙둥이).
This name holds deep sentimental value, as it is a callback to an affectionate term the members used for their fans during their original promotional period in 2016. The formal adoption of “Angdungi” serves as a tribute to the loyalty of the fans who have kept the group’s memory alive over the past nine years. It symbolizes a renewed bond between I.O.I and their supporters as they embark on this exciting new chapter together.
As May 19 approaches, the anticipation surrounding I.O.I : LOOP continues to grow. This comeback is more than just a new album release; it is a celebration of resilience, friendship, and the enduring power of K-Pop. Whether you are a long-time fan who followed them from their Produce 101 days or a newer listener discovering their magic for the first time, I.O.I’s return is undoubtedly one of the most significant musical events of 2026.
