I.O.I placed Jeon Somi and Kim Doyeon at the center of its comeback coverage after releasing the music video teaser for “Suddenly” at midnight on May 6, 2026 through the group’s official social media channels. The teaser, widely described in Korean entertainment reports as a sudden kiss scene, shows Jeon Somi approaching Kim Doyeon and briefly kissing her before Kim reacts in surprise and collapses to the floor.1
The I.O.I Suddenly teaser arrives ahead of the group’s new mini album, “I.O.I : LOOP,” which is scheduled for release on May 19, 2026. The comeback has also drawn attention because it is tied to I.O.I’s 10th anniversary activities and is being carried out as a nine-member promotion.1
Jeon Somi and Kim Doyeon Kiss Scene Frames the Teaser

Reports from multiple Korean outlets focused on the same central moment: Jeon Somi moves toward Kim Doyeon, who is standing against a wall, and gives her a short, unexpected kiss. Kim Doyeon then appears startled and sits down or sinks to the ground, creating the teaser’s main visual turn.2
The scene appears at the beginning of the short video, setting the tone before the teaser moves further into the track’s atmosphere. JoyNews24 described the sequence as opening with Jeon Somi approaching Kim Doyeon and leaving a kiss, while also identifying “Suddenly” as a synth-pop track built around waves of longing.3
iMBC Entertainment similarly reported that the teaser contrasts Jeon Somi’s sudden kiss with Kim Doyeon’s shocked facial expression, using the brief moment to create tension within the short-form video.4 The reporting available does not include a full music video plot summary, so the teaser’s wider narrative context remains limited to the scene and album details already released.
The wording used by several Korean outlets has emphasized the unexpected nature of the moment. However, the core confirmed details are narrower: the teaser has been released, it includes a brief kiss between Jeon Somi and Kim Doyeon, and the scene has become the main focus of immediate coverage around I.O.I’s return.
Kim Doyeon Discusses the Behind-the-Scenes Idea
A separate report from Sports Chosun added behind-the-scenes context from Kim Doyeon’s comments on a fan communication platform. Kim reportedly said the kiss scene was her idea, stating, “You may not believe it, but this was my idea.”5
She also indicated that the scene was filmed several times, with another quoted comment translated as, “We did many takes.”5 In the same report, Kim described the suggested direction behind the moment with the line, “Instead of hitting, let’s kiss.”5
Those comments give the teaser additional production context, but the available source material does not provide the full conversation, the director’s explanation, or a complete account of how the scene was finalized. The confirmed point is that Kim Doyeon publicly connected the moment to her own suggestion and said more than one take was filmed.
The scene’s reception has been shaped by both the footage itself and the later comments. Coverage has treated the kiss as the teaser’s main talking point, while also linking it to the larger comeback schedule for I.O.I’s 10th anniversary project.
Album Release and Concert Schedule
“I.O.I : LOOP” is identified in reports as the group’s third mini album, with “Suddenly” serving as the title track. Maeil Business Newspaper reported that Jeon Somi participated in writing lyrics for the song and described the title track as synth-pop.1
The album is scheduled for release at 6 p.m. on May 19, 2026, according to CBS No Cut News and Sports Chosun.6 The schedule places the teaser less than two weeks before the new music release, giving the group a compact promotional window centered first on the “Suddenly” video preview and then on the album rollout.
I.O.I is also scheduled to hold concerts from May 29 to May 31, 2026 at Jamsil Indoor Gymnasium in Seoul.6 JoyNews24 also reported the same May 29-31 concert period following the album release, placing the live dates shortly after the comeback.3
The group’s 10th anniversary return is taking place as a nine-member activity, a detail reported alongside the teaser release and album information.1 The sources provided do not list the full nine-member lineup in the available summaries, so the article does not expand beyond the confirmed number.

For now, the confirmed comeback coverage centers on three points: the “Suddenly” teaser’s Jeon Somi and Kim Doyeon kiss scene, Kim Doyeon’s reported comments that the idea came from her, and the scheduled release of “I.O.I : LOOP” on May 19, 2026. With concerts set for May 29-31, the teaser functions as the first major visual marker in I.O.I’s 10th anniversary promotion period.
