The table this is written from: /what-moves-english-reading
Seo In-young averaged 98.3 English Wikipedia reads a day for the 23 days before 12 September, 2026. The day after all four original members of her 2000s girl group Jewelry shared a stage for the first time in two decades, that number hit 662 — 6.7 times her baseline.
What happened
Nate News reported that Jewelry’s full original lineup — Park Jung-a, Lee Ji-hyun, Seo In-young, and Cho Min-ah — performed together for the first time in 20 years on KBS2’s long-running music show “Immortal Songs” (불후의 명곡), episode 773, broadcast 12 September. The stage was part of the “2026 NEW WAVE Festival in Ulsan,” recorded in front of roughly 10,000 people at Ulsan Taehwa River National Garden. The group ran through its 2000s hits, including “One More Time,” “Niga Cham Joha,” “Tonight,” and “Super Star.” Seo In-young was quoted saying the reunion made her tear up — “Is it menopause? I’m crying again.”

A reunion, not a comeback
This is a different shape of event from the drama premieres and cameos we usually track in this series — no new single, no new show, just four members who had not performed together in 20 years sharing one stage for one night. The reading rose the day it aired and kept rising the day after, the pattern we’d expect from word of mouth about a broadcast rather than a slow-building news cycle.

What we left out, and why
- Any reading of this as proof a one-off reunion stage has lasting attention value beyond this one-week window.
- The other three members' reading in the same window — we measured Seo In-young only here.
- Any day after 19 September — Wikimedia had not yet published later days when we pulled this data.
