The K-pop Reunion That Nobody Saw Coming — But Everyone Wanted
On May 19, 2026, I.O.I — the legendary project girl group formed through Mnet’s ‘Produce 101 Season 1’ — releases their third mini album ‘I.O.I: LOOP,’ marking their 10th anniversary since debut. For longtime K-pop fans, this is one of the most emotionally significant comebacks in recent memory.
Who Is I.O.I? A Quick History for New Fans
I.O.I debuted in May 2016 as a temporary project group formed through the survival show ‘Produce 101.’ Eleven members were selected by public vote from 101 trainees across various Korean entertainment agencies. The group’s debut was explosive — their song ‘Dream Girls’ became an instant hit, and their limited-time status made every performance feel precious.
The group officially disbanded in January 2017 after just seven months together. Their members went on to significant solo and group careers: Chung Ha became one of K-pop’s top soloists, Jeon Somi built a successful career under THEBLACKLABEL, and others found success in groups like WJSN, DIA, and gugudan. Despite disbanding, I.O.I maintained a passionate global fanbase who never stopped hoping for a reunion.
They reunited briefly in 2021 for a special project marking their 5th anniversary, releasing ‘Yummy Yummy’ and performing at concerts. Now, ‘LOOP’ marks their most substantial return yet.
What’s Special About ‘I.O.I: LOOP’
The third mini album’s title ‘LOOP’ is a nod to the cyclical nature of the group’s story — endings that become beginnings. In a deeply personal touch, member Jeon Somi participated in writing the lyrics for the title track, bringing her evolved artistry back to her roots. This has generated enormous fan excitement.
Following the album release, I.O.I will hold a solo concert for three nights — May 29, 30, and 31 — at Seoul’s Jamsil Indoor Gymnasium, before embarking on an Asia tour. Tickets sold out rapidly.
Why This Comeback Resonates Beyond K-pop
I.O.I’s return is more than a music release — it’s a cultural moment. For a generation of fans who grew up watching ‘Produce 101,’ seeing these members perform together again is an experience that transcends typical fandom. The ’10th anniversary’ framing also makes this accessible to new fans who want to understand K-pop history. If you’ve never listened to I.O.I before, now is the perfect time to start.
