I.O.I Suddenly completed a triple crown on MBC’s Show! Music Core after I.O.I placed first with “Suddenly” on the July 4, 2026 broadcast. The result marked the group’s third No. 1 on the program for the song, following wins recorded on June 13 and June 27.1
The July 4 episode listed I.O.I’s “Suddenly,” aespa’s “LEMONADE,” and ATEEZ’s “BAD” as the first-place nominees, with I.O.I ultimately taking the trophy.2 Sports Today reported that the group finished with a total score of 7,518 points on the broadcast.3
I.O.I Suddenly Triple Crown Confirmed

The triple crown gives “Suddenly” a clear broadcast milestone within I.O.I’s 10th-anniversary activity cycle. OSEN reported that the song’s three Show! Music Core wins came on June 13, June 27, and July 4, completing the program’s triple crown benchmark for the track.1
MBCkpop also published a July 4 clip titled for the first week of July No. 1 winner, identifying “I.O.I (아이오아이) – Suddenly (갑자기)” as the related Show! Music Core content from the MBC260704 broadcast.4 The clip’s listing aligns with the program result reported by entertainment outlets on the same date.
The group’s July 4 appearance also carried a separate context: members were at the broadcast venue to support Choi Yoo-jung’s solo comeback stage. OSEN, citing Jung Chae-yeon’s social media post, reported that the members went to support Yoo-jung and ended up receiving the No. 1 trophy together. Jung wrote, “We went to cheer for Yoo-jung and were happy to receive the No. 1 award in person.”1

July 4 Broadcast Result and Acceptance Remarks
Choi Yoo-jung gave the acceptance remarks during the July 4 broadcast after appearing as a solo-stage performer, while I.O.I members were present to support her.3 Her comments linked the award to the group’s return and the long interval since its previous full-group activity.
In the broadcast remarks reported by Sports Today, Choi said she was happy that the group reached No. 1 with an album released after 10 years. She also added, “We may suddenly appear again someday,” a line that echoed the Korean title of “Suddenly.”3
The reporting around the result presented the July 4 win as both a music-show achievement and a notable moment in I.O.I’s anniversary project. The win was not described as an isolated chart event; it followed the song’s earlier broadcast wins and the broader reception of the comeback release.
Album Context Behind “Suddenly”
“Suddenly” is the title track from I.O.I’s third mini album, “I.O.I : LOOP,” which was released at 6 p.m. on May 19, 2026. Star Today reported that the album opened the group’s full-group activity after roughly nine years, and described “Suddenly” as a synth-pop song expressing memory and longing. The report also noted that Jeon Somi participated in writing the lyrics.5
SBS Entertainment News later reported that the title track reached No. 1 on Melon TOP100 and HOT100, while the “Suddenly” challenge spread on short-form platforms during the album’s activity period.6 Those results helped frame the Show! Music Core triple crown as part of a wider comeback performance rather than a single-program outcome.
The source-backed record now places “Suddenly” among the defining measurable results of I.O.I’s 10th-anniversary return: a May 19 album release, chart performance reported in late May, and three Show! Music Core wins culminating on July 4.65

The July 4 Show! Music Core result confirmed I.O.I’s “Suddenly” as a triple-crown winner on the program, with the final win coming against aespa’s “LEMONADE” and ATEEZ’s “BAD” and a reported total of 7,518 points. The milestone closes a clearly documented three-win run for the song on June 13, June 27, and July 4, 2026.
