On May 9, JTBC released a teaser preview for episode 529 of the variety show 'Knowing Bros,' featuring the highly anticipated reunion of I.O.I as they celebrate their 10th debut anniversary.

Formed through a hit audition program in 2016, I.O.I became one of the most influential project girl groups in K-pop history. Despite promoting together for only one year, the group left a lasting impact with its strong popularity and cultural influence. The newly released teaser has already sparked excitement among fans eager to see the members reunited once again.

Notably, I.O.I previously appeared on 'Knowing Bros' in 2016 as their final full-group variety show appearance before ending official activities. At the time, the members displayed memorable chemistry with the cast members, creating iconic moments for viewers. Returning nearly a decade later, the members are expected to showcase more mature wit and entertaining stories shaped by their individual careers and experiences.

The upcoming broadcast will feature Lim Na Young, Kim Chung Ha, Kim So Hye, Yoo Yeon Jung, Choi Yoo Jung, Kim Do Yeon, and Jeon So Mi. Together, they are expected to reflect on the past 10 years, share behind-the-scenes memories, and reveal the stronger bond they have maintained over time.

For longtime supporters of the group, the reunion marks a meaningful and nostalgic moment celebrating I.O.I’s enduring legacy.

JTBC’s 'Knowing Bros' airs every Saturday at 9 PM KST.
