IOI took first place on MBC’s Show! Music Core with “Suddenly” on the June 13, 2026 broadcast, extending the chart and broadcast momentum of the group’s 10th-anniversary comeback. The song, also referred to in English as IOI Suddenly, won without the group appearing on the program that day, with a reported total score of 7,815 points.1
The first-place candidates on the broadcast were IOI’s “Suddenly,” ILLIT’s “It’s Me,” and aespa’s “Lemonade.” IOI led the ranking, followed by aespa in second place with 5,901 points and ILLIT in third place with 5,590 points.1
IOI Wins First Place on Music Core

The June 13 result marked another major outcome for “Suddenly” after IOI completed promotional activity tied to its debut 10th anniversary. Topstarnews reported that the members showed an emotional reaction to receiving a music-show win after activities had ended, and included Kim Se-jeong’s brief response: “I’m really happy. Really, really.”2
The result was notable because the win came after the group had already wrapped up its anniversary promotions, not during an active appearance on the broadcast. The available reports identify the award as a Show! Music Core first-place trophy for “Suddenly,” rather than a new comeback schedule or additional promotional announcement.12
| Rank | Artist | Song | Reported Score |
|---|---|---|---|
| 1 | IOI | “Suddenly” | 7,815 |
| 2 | aespa | “Lemonade” | 5,901 |
| 3 | ILLIT | “It’s Me” | 5,590 |
The final score gap placed IOI 1,914 points ahead of aespa and 2,225 points ahead of ILLIT. Those figures come from the reported broadcast ranking, which listed the three nominees and their final totals for the June 13 episode.1
From Album Track to Broadcast Winner
“Suddenly” is the title track from IOI’s third mini album, I.O.I : LOOP, released on May 19, 2026. Newsen described the song as the title track of the new album and reported that it had reached No. 1 on Melon’s Top 100 after release, framing the comeback as a return after a long gap.3
The song’s commercial movement was reported before its music-show win. Hanteo News noted that “Suddenly” entered Melon’s real-time Top 100 at No. 100 during its first release window, then rose to No. 42 on May 20 and No. 22 on May 22. The report pointed to the spread of challenges and music-show stages as factors connected to the song’s upward movement.4
Additional coverage from ize reported that IOI released I.O.I : LOOP on May 19 and that “Suddenly” reached No. 1 on Melon TOP100 on the morning of May 29. The same report described the comeback as the group’s first full-group activity in nine years and noted that stable live performances and stage presentation drew fan response.5
MBCkpop, MBC’s official K-pop YouTube channel, also posted an official Show! Music Core stage clip for “Suddenly” from the May 23, 2026 broadcast. The clip documents the song’s music-show activity before the June 13 first-place result, though official embeds are not included here.6
What the Result Shows
The source-backed timeline places the Show! Music Core win after several measurable steps: the album release on May 19, early movement on Melon’s real-time Top 100, a reported Melon TOP100 No. 1 on May 29, and the June 13 broadcast trophy. Each item points to a sustained run rather than a single-day result.354
At the same time, the reports do not establish new group schedules beyond the completed 10th-anniversary activity. The clearest available facts are the broadcast ranking, the point totals, the song’s album connection, and the member reaction after the win. That makes the June 13 result a confirmed music-program achievement for “Suddenly,” rather than evidence of an extended promotion period.

The first-place finish for IOI on Show! Music Core adds a broadcast trophy to the documented chart performance of “Suddenly.” With 7,815 points and a win over aespa and ILLIT on the June 13 episode, the song’s post-release run continued beyond the group’s completed anniversary promotions.
