IU postponed her sixth full-length album and the September 2026 Goyang Stadium concert on July 20, 2026, citing an ear condition — nine days after actor Heo Nam-jun was confirmed as the male lead in the music video for her next title track.
What's confirmed about IU's 2026 comeback MV — and what stalled it?
Two facts are on the record, and they point in opposite directions. On July 11, 2026, Heo Nam-jun's agency H.SOLID confirmed to Korean media that he would appear in the music video for the title track of IU's forthcoming album, with filming scheduled for August 2026 . On July 20, 2026, EDAM Entertainment announced that IU was postponing her sixth full-length album and the September Goyang Stadium concert because of patulous Eustachian tube dysfunction .
Quick Answer: EDAM Entertainment postponed IU's sixth album and her September 2026 Goyang Stadium concert on July 20 over an ear condition — nine days after Heo Nam-jun was confirmed on July 11 for the album's title-track music video, with an August shoot planned. As of late August 2026, the MV's status remains unconfirmed.
What no agency has addressed is the music video itself. The postponement statement covered the album and the concert schedule; it said nothing about whether the August shoot with Heo went ahead, slid, or was dropped. IU has said studio recording was already finished — jacket photography done, most mixing complete — and that the delay was driven by touring and promotion rather than production . That leaves room for the shoot to have happened quietly, but it is not confirmed either way.

One practical note for fans tracking this: no tickets for the Goyang shows had gone on sale, so the postponement triggered no refunds. Any coverage still framing a September 2026 comeback in the present tense is working from the pre-July 20 timeline.
Heo Nam-jun and IU's collaboration history: two music videos and a drama cameo
Heo Nam-jun's July 2026 casting is not a first meeting but the latest entry in a working relationship that began in May 2025 . That year he played IU's male lead in the music video for "Never Ending Story" (네버 엔딩 스토리), the title track of her third remake album A Flower Bookmark 3 (꽃갈피 셋). The video was staged as a tribute to the 1998 Korean film Christmas in August, with IU evoking Shim Eun-ha's character and Heo taking the role originated by Han Suk-kyu. According to Korean reporting, IU extended the offer herself, before Heo was widely known to the general public.
Their second meeting came on April 11, 2026, when Heo made a special appearance in episode 2 of the MBC drama 21st Century Grand Lady (21세기 대군부인) — rendered by some English outlets as "Perfect Crown" — playing IU's arranged-date partner (source: Sports Khan, 2026-04) .
That cameo is why outlet counts diverge. Publications tallying only music-video work call the July 2026 project the pair's second collaboration; tenasia's July 11 report on the new video instead frames it as their "third meeting" (세 번째 만남), counting the drama cameo alongside both videos .
Heo has described himself as a longtime IU fan. Recalling the 2025 shoot, he said:
"Every day leading up to the shooting date was like a party. Just knowing that IU knows I am alive in this world made me feel there is nothing left to regret," — Heo Nam-jun, actor (source: Star News Korea, 2026-07)
His visibility rose further through the SBS drama 멋진 신세계 (translated variously as "Wicked World" or "Brave New World"), which concluded June 20, 2026 . His next confirmed project is tvN's 고래별 ("Whale Star"), a webtoon adaptation set during the Japanese colonial occupation about a man who sacrificed everything for the independence movement and the woman who protects him. Despite that schedule, his agency H.SOLID said he accepted IU's offer, with filming set for August 2026.
Why IU postponed the album and the Goyang concerts
IU postponed her sixth full-length album and her entire concert schedule on July 20, 2026, nine days after the Heo Nam-jun casting was confirmed, because of worsening patulous Eustachian tube dysfunction (이관개방증) — a condition in which the tube connecting the middle ear to the throat stays open, distorting how a singer hears her own voice . EDAM Entertainment said the decision covered the September Goyang Stadium show, all subsequent tour dates, and the album release .
"We and IU recently judged that her ear condition makes it difficult to proceed with performances… after careful discussion prioritizing her health, we decided to adjust the September Goyang Stadium performance and subsequent concert schedule, as well as the sixth full-length album schedule." — EDAM Entertainment statement, July 20, 2026 (source: Seoul Shinmun)
The agency added that the condition is "not severe enough to interfere significantly with daily life," framing the postponement as a decision to perform in optimal condition rather than a medical emergency . Writing to fans on the fan platform Berriz, IU said her chronic symptoms had persisted day and night for several days, making it hard to find her singing condition. She cited the weather as a factor and said "work greed" over recent years may have led her to overexert herself.
Importantly, the recording itself was finished. IU confirmed that studio work was complete, jacket photography was done, and most mixing had been handled with a new production team . The album's promotion plan was built around the concerts and tour, so the release slid with them — this is a promotion and touring delay, not a production failure.
What the postponement cost, in concrete terms:
- First Korean female soloist to headline Goyang Sports Complex Main Stadium — the September show would have set that mark .
- First Korean artist to fill all three of Jamsil Olympic Stadium, Seoul World Cup Stadium (Sangam), and Goyang — a stadium sweep no domestic act had completed .
- First stand-alone concert since September 2024, when she closed The Winning encore run at Seoul World Cup Stadium .
"I feel so heavy-hearted and sorry that I can't keep my concert promise… I'm sorry for ruining the second half of the year for all of us," IU wrote, pledging to return as quickly as possible . Because no tickets had gone on sale for the Goyang date, no refund process was required — a detail that spared fans the usual cancellation logistics.
What's next: MV status, ticketing, and IU's return timeline
IU's return window points to early 2027, with no fixed date issued by EDAM Entertainment as of late August 2026 . The agency has framed the pause as precautionary rather than an emergency, stating that the patulous Eustachian tube dysfunction is "not severe enough to interfere significantly with daily life" and that the schedule was adjusted so she could perform in optimal condition . For fans, that distinction matters: this is a rescheduling, not a retirement or an indefinite hiatus.
On the logistics side, there is nothing for ticket holders to do. No sales had opened for the September Goyang Sports Complex Main Stadium show before the July 20, 2026 announcement, so no refunds or cancellations were processed . When the tour is rebooked, fans should expect a fresh on-sale cycle rather than a transfer of existing reservations, and international fans planning travel around a Goyang date have no sunk booking to unwind.
The music video with Heo Nam-jun is the one genuinely open question. His agency H.SOLID confirmed on July 11, 2026 that filming was scheduled for August , and IU has said studio recording was finished, jacket photography complete, and most mixing done . Neither EDAM nor H.SOLID has said publicly whether the shoot went ahead, was pushed, or was shelved. Because the delay was driven by touring and promotion rather than production problems, a completed video sitting on the shelf is plausible — but plausible is not confirmed.
The concrete takeaway: treat any "IU September 2026 comeback" framing as outdated, expect an EDAM announcement rather than a ticketing site to break the news first, and watch for a rescheduled Goyang date as the signal that the album — and the Heo Nam-jun video attached to it — is finally moving.
Frequently asked questions
Is Heo Nam-jun still going to be in IU's comeback music video?
Unresolved, not cancelled. H.SOLID confirmed on July 11, 2026 that Heo Nam-jun would star in the music video for the title track of IU's next album, with filming scheduled for August 2026 . EDAM Entertainment's July 20 postponement announcement covered the album and concerts but said nothing about the video . As of late August 2026, neither agency has stated publicly whether the shoot went ahead, was pushed back, or was dropped.
Why was IU's 2026 comeback postponed?
EDAM Entertainment cited worsening patulous Eustachian tube dysfunction (이관개방증), announcing on July 20, 2026 that IU (Lee Ji-eun, 33) would postpone the September Goyang Stadium concert, all subsequent tour dates, and her sixth full-length album . The agency said the condition is "not severe enough to interfere significantly with daily life" but made performing in optimal condition difficult. Writing to fans on the Berriz platform, IU said her chronic symptoms had persisted day and night for several days, pointed to weather as a factor, and acknowledged she may have overexerted herself out of "work greed" in recent years .
Is this the second or third time Heo Nam-jun and IU have worked together?
Both counts appear in Korean coverage, and the gap is definitional: whether a drama cameo counts as a collaboration. The verified chronology has three points of contact — the May 2025 music video for "Never Ending Story," the title track of IU's remake album A Flower Bookmark 3; a special appearance in episode 2 of MBC's 21st Century Grand Lady on April 11, 2026, where Heo played IU's arranged-date partner; and the music video announced on July 11, 2026 . Outlets counting music videos only call it the second; those including the cameo call it the third in two years.
Do I need a refund for the Goyang concert?
No. Tickets for the September 2026 Goyang Sports Complex Main Stadium show had not gone on sale when EDAM Entertainment announced the postponement on July 20, 2026, so no purchases were made and no refund process was required . Fans holding no transactions simply have nothing to reclaim. When the tour is rescheduled, expect a fresh on-sale cycle announced through EDAM rather than any carry-over of prior queue positions or presale registrations.
When will IU release her sixth album?
There is no confirmed release date. Reports following the July 20, 2026 postponement point to an early-2027 target, contingent on IU's recovery and on rescheduled tour dates . The recording itself is not the bottleneck: IU told fans that studio work was already finished, jacket photography was complete, and most mixing was done with a new production team, but that the album's promotion plan was built around concerts . She pledged to return "as quickly as possible."
