I.O.I’s ‘Suddenly’ Secures Triple Crown Before Fourth Music-Show Win

I.O.I’s reunion single “Suddenly” moved from a music-show triple crown to a fourth trophy in July, extending the chart and broadcast run of the group’s 10th-anniversary comeback. The title track first completed three straight wins on MBC’s “Show! Music Core” on July 4, then added a No. 1 finish on SBS “Inkigayo” on July 12 with 5,343 total points.¹²

The results followed the group’s return with the third mini album “I.O.I : LOOP,” a project tied to the broader IOI reunion and the group’s first new album in nine years. The comeback was reported as a nine-member activity, excluding Kang Mina and Zhou Jieqiong, and centered on “Suddenly” as the album’s title track.³⁴

‘Suddenly’ Triple Crown Becomes a Four-Win Run

The central result came on MBC’s “Show! Music Core,” where “Suddenly” ranked first on June 13, June 27, and July 4. The July 4 broadcast confirmed the song’s third consecutive “Music Core” win, giving I.O.I a triple crown on the program.¹⁵

The July 4 appearance also carried a separate stage context. I.O.I members visited the “Show! Music Core” set to support Choi Yoojung’s solo comeback, and Choi accepted the trophy on behalf of the group while appearing for her own performance. OSEN reported that eight members, excluding Yoo Yeonjung, joined the encore stage after the win.⁵

The winning streak continued beyond “Music Core.” On July 12, I.O.I took first place on SBS “Inkigayo” with “Suddenly,” scoring 5,343 points and finishing ahead of aespa and RESCENE. That result brought the track to four total music-show wins.²

Choi Yoojung’s acceptance remarks also framed the reunion as a temporary but meaningful project. After the “Inkigayo” win, she said, “Thank you so much for loving this project we came together for after a long time.”² After the triple crown, she told fans, “If you keep missing us, we may suddenly appear again someday.”¹

Album, Chart and Concert Context

“Suddenly” was introduced before release as the title track of I.O.I’s third mini album “I.O.I : LOOP.” The song was described as synth-pop, and Jeon Somi was credited with participation in its lyrics. Members including Jeon Somi, Yoo Yeonjung, and Chungha were also reported to have participated in work on other tracks.⁴

The single’s early commercial signal came on May 29, when “Suddenly” topped Melon Top 100 at 8 a.m. The timing coincided with the opening day of I.O.I’s Seoul concert run, which was scheduled from May 29 to 31 at Jamsil Indoor Stadium in Seoul.⁶

That concert marked I.O.I’s first group stage in nine years and was presented under the title “2026 I.O.I Concert Tour: LOOP in Seoul.” The set included the new song “Suddenly” alongside known tracks including “Pick Me,” “Dream Girls,” “Very Very Very,” and “Downpour.”³

The reunion was connected to the group’s 10th anniversary and proceeded with nine members. Yonhap News reported that Kang Mina and Zhou Jieqiong were not part of the comeback lineup. During the concert, Kim Doyeon said, “We were able to gather again after nine years thanks to the fans.”³

Current Status of the I.O.I Reunion Track

By July 12, the available record showed “Suddenly” with a Melon Top 100 No. 1, a “Show! Music Core” triple crown, and four total music-show wins. Those milestones make the song the clearest documented performance marker of the 2026 I.O.I reunion campaign in the provided reports.

The available reports do not provide additional confirmed future promotion dates after the July 12 “Inkigayo” win. Based on the confirmed record, “Suddenly” has already moved beyond a single-program triple crown into a broader four-win music-show run, while also anchoring I.O.I’s nine-member anniversary comeback and Seoul concert return.
