IOI Wanna One Reunion Effect

Groups I.O.I and Wanna One are reuniting after 9 and 7 years, respectively, not just evoking nostalgia but also attracting new fan bases. Their reunions are drawing attention as a new box office draw.

Amidst persistent reunion requests from past fans, the members have come back together, making project group reunions a reality. This stimulates the nostalgia of existing fans while simultaneously attracting the interest of new fan bases. Given their explosive popularity and strong fandom built even within short activity periods, their continued influence is evident, with high interest generated simply by news of the members' current activities or broadcast appearances.

I.O.I showcased their enduring power as the title track 'Suddenly' from their 10th anniversary mini-album 'I.O.I : LOOP' topped the Melon chart. I.O.I, formed through 'Produce 101' Season 1 in 2016, was loved for hit songs like 'Very Very Very' and 'Dream Girls'. Although Zhou Jieqiong and Kang Mina did not participate in this reunion, they displayed their unchanged presence despite the long hiatus and received enthusiastic responses.

I.O.I's reunion also extended to social media, with the 'Suddenly' dance challenge, featuring various artists and celebrities such as Kim Min-seok of MeloMance, Mingyu of Seventeen, and Sana and Jihyo of TWICE, gaining traction. Notably, achieving the number one spot on the music charts on the first day of their solo concert, '2026 I.O.I Concert Tour: LOOP,' held at the Jamsil Indoor Gymnasium in Seoul, holds significant meaning. The members expressed their emotion, stating, "It's too perfect."

Wanna One also proved their continued relevance through their reunion project. They officially began their activities on the 6th through '​WANNA ONE GO : Back to Base'. Wanna One, who debuted through 'Produce 101 Season 2' in 2017, enjoyed a sensational popularity with hit songs like 'Energetic' and 'Beautiful'.
