FLASHBACK · I.O.I 💗

The Girls We Once Chose Have Returned

The eleven chosen by the ‘nation’s producers’ returned after 10 years with ‘I.O.I : LOOP’. The title track ‘Suddenly’ rode a wave of public support the month after release, climbing back to #1 on the Hanteo streaming chart.

Our choice was still the right one.

WHY REVIVAL ✦

Why They Reunited in the First Half of 2026

ANALYSIS 01

The anniversary effect

Milestones like the 10th, 15th, or 20th anniversary make it easy to package albums, concerts, fan-meetings, and content.

10th · 15th · 20th anniversaries
ANALYSIS 02

A preference for proven IP

In a market of rising rookie-launch costs and competition, an act that already has a name and a story becomes a low-risk asset to restart.

10팀
ANALYSIS 03

Mature fandom spending power

Former fans are now a generation that can spend on concerts, merch, limited editions, and fan-meetings.

10 years on average
ANALYSIS 04

Platform-style reunions

An environment now exists to call a fandom back with YouTube, reality, short-form, and social media alone — no album required.

2팀
ANALYSIS 05

Reclaiming an unfinished story

Stages they never got to fully show — short runs, disbandments, hiatuses, music-show limits — reopen in 2026.

I.O.I · 10 years
ANALYSIS 06

Military breaks, contracts & solo careers align

Members scattered for years reached a moment when solo careers, contracts, and post-service timing let them regroup for a short project.

2026 H1
“The reunions of 2026 weren’t simple nostalgia. Anniversaries, a matured fandom, proven IP, and stories left untold interlocked — and names that had stood still were called back to the stage.”

The Second Half: Something Truly Big Is Coming

The name says it all — BIGBANG. In the second half of 2026, K-pop doesn’t grow quietly; it explodes with a full-group world tour.
