I.O.I Suddenly on Melon: Reunion Track Enters Top 10 After May Comeback

I.O.I Suddenly has entered the Melon real-time Top 100 top 10, with the reunion title track peaking at No. 10 after rising three places on the chart. The chart move follows the May 19 release of I.O.I’s third mini album, “I.O.I : LOOP,” and the music video for “Suddenly,” marking a 10th-anniversary reunion comeback for the project group. ¹

The release has drawn attention because it brings I.O.I back as a group project years after its original run, while also placing the title track inside one of Korea’s closely watched domestic music rankings. The song’s Melon entry gives the comeback a measurable chart marker beyond the album rollout and video release. ¹

I.O.I Suddenly Reaches Melon Top 10

Allkpop reported on May 25, 2026, that “Suddenly” entered Melon’s real-time Top 100 top 10 and reached No. 10 after a three-place rise. The report connected the movement to renewed public attention around I.O.I’s 10th-anniversary reunion and the release of the track’s music video. ¹

The chart placement came less than a week after the album’s release. “I.O.I : LOOP” was released on May 19 at 6 p.m. KST across major music platforms, with “Suddenly” serving as its title track. ² Apple Music also lists “Suddenly” as a song by I.O.I from “I.O.I 3rd MINI ALBUM (I.O.I : LOOP) – EP,” with a release date of May 19, 2026. ³

The available source material does not provide additional Melon positions beyond the reported No. 10 peak, nor does it provide sales totals, streaming counts, or unique listener figures. For that reason, the confirmed chart fact is limited to the real-time Top 100 top 10 entry and the reported No. 10 peak.

Album Release and Track Details

“Suddenly” is described in the source material as a synth-pop title track. Jeon Somi participated in writing the lyrics, adding member involvement to the reunion release’s creative credits. ² Soompi also reported the May 19 release of “I.O.I : LOOP” and the music video for “Suddenly,” while describing the song as a synth-pop track and noting Jeon Somi’s lyric participation. ⁴

The album’s pre-release activity began before the full drop. OSEN, carried by ChosunBiz, reported that I.O.I released a highlight audio preview for “I.O.I : LOOP” through official channels on May 13. That report said the mini album contains six tracks and highlighted member participation, including Jeon Somi on “IOI (Where My Girls At)” and the title track “갑자기,” the Korean title corresponding to “Suddenly.” ⁵

Billboard Philippines listed the six tracks on “I.O.I: LOOP” as “IOI (Where My Girls At),” “Suddenly,” “SPF 100+,” “IF I,” “Then, Now and Forever,” and “Goodbye With A Smile.” The same report said I.O.I released the “Suddenly” music video together with the six-track mini album. ⁶

The title track therefore sits within a compact album package built around the reunion theme, with the available reporting emphasizing both the group narrative and member participation. The provided sources do not include full production credits, detailed composer information, or a complete breakdown of each member’s recording role.

Reunion Lineup and Seoul Schedule

The comeback is framed across the sources as a 10th-anniversary reunion. Billboard Philippines reported that nine members joined the reunion, while Kang Mina and Zhou Jieqiong did not participate because of prior commitments. ⁶ The source material does not add further details about those commitments.

A three-day Seoul concert run is also part of the reunion schedule. Allkpop reported that I.O.I would hold concerts at Jamsil Indoor Stadium from May 29 to 31, following the release of “I.O.I : LOOP” and “Suddenly.” ² Because the current date is May 25, 2026, those concert dates remain upcoming in the source-backed timeline.

The comeback rollout also included teasers, concept photos, a mood film, and a promotion scheduler before the album release, as documented in Soompi’s update thread. ⁴ Those promotional materials preceded the May 19 release date and helped establish the schedule for the group’s return.

The confirmed picture is narrow but clear: I.O.I returned with “I.O.I : LOOP” on May 19, 2026, placed “Suddenly” as the synth-pop title track, and saw the song reach No. 10 on Melon’s real-time Top 100 after its release. With Seoul concerts scheduled for May 29 to 31, the Melon Top 10 entry gives I.O.I’s reunion comeback a defined chart milestone ahead of its next major live dates.
