FIFTY FIFTY released the pre-release track “STARSTRUCK” at 6 p.m. KST on May 15, 2026, through major online music platforms, opening the rollout for the group’s fourth mini album, “Imperfect-I’mperfect.” The release positions FIFTY FIFTY STARSTRUCK as the first confirmed music from the upcoming project before the album’s official arrival on June 1, 2026.1
The single has been introduced as part of the lead-up to the group’s next comeback cycle. Multiple Korean entertainment reports identify “STARSTRUCK” as a pre-release track, not the full album release, with “Imperfect-I’mperfect” scheduled to follow a little more than two weeks later.2
FIFTY FIFTY STARSTRUCK Release Details

The central confirmed detail is the timing: “STARSTRUCK” was set for release at 6 p.m. KST on May 15, 2026. EDaily reported that the track would be made available through various online music sites, while Star Today also described it as a pre-release song from FIFTY FIFTY’s fourth mini album.13
The song title refers to the state of being fascinated by a star or feeling admiration and awe toward a celebrity, as described in reporting that cited the agency Attrakt. That meaning gives the release its clearest stated conceptual frame, while the agency’s broader explanation presents the track as a signal of the group’s identity within the new comeback cycle.2
An Attrakt representative described the song as one marked by “strong electro synth sound” and “sensuous lyrics” that create an unusual atmosphere.1 Star Today likewise reported that the agency emphasized the track’s unusual lyrical mood and polished sound, while framing it as music intended to reinforce the group’s unique identity.3
The release also marks a return after the group’s November 2025 digital single “Too Much Part 1.” EDaily and KBS WORLD Korean both reported that the new mini album comeback comes roughly seven months after that prior digital single, giving the May 15 pre-release a defined place in the group’s discography timeline.14

Mini Album Rollout Continues Toward June 1
“Imperfect-I’mperfect” is the project at the center of the rollout. News1, carried by Financial News, reported that the fourth mini album is officially scheduled for release on June 1, 2026, with “STARSTRUCK” preceding it as a lead-in single.2
Bridge Economy reported through Nate News that Attrakt had released the comeback schedule through official social media channels. The scheduler placed “STARSTRUCK” first on May 15, followed by additional teaser content including a highlight medley and music video teasers.5
The agency’s stated reason for releasing the track before the full album was also linked to fan support. In a quoted agency statement, the company said it decided on the pre-release “for fans who have supported the comeback with unwavering hearts.”5 The statement frames the May 15 release as an advance step before the formal comeback rather than a standalone promotional event.
Reports also described the album’s message in terms of accepting even imperfect parts of oneself. Bridge Economy said “Imperfect-I’mperfect” carries a message about embracing imperfection, a theme that appears to connect the album title with the wider comeback concept.5
KBS WORLD Korean reported that the comeback scheduler was posted to the group’s official social media at midnight on May 12, 2026. The scheduler included the “STARSTRUCK” pre-release as well as later promotional content in the run-up to the June 1 album release.4
Related Content Extends the Comeback Concept
The “STARSTRUCK” rollout also connects with video and short-form content tied to the upcoming album’s world. Cineplay reported that FIFTY FIFTY appears in the KITZ short-form platform content “After-School Exorcism Club,” marking the group’s first acting challenge.6
According to Cineplay, a music video using “STARSTRUCK” as background music was scheduled for release on the KITZ YouTube channel at 6 p.m. KST on May 15, 2026. The main drama was listed for release on KITZ on May 22, 2026, and the content was described as sharing a world with the June 1 album “Imperfect-I’mperfect.”6
That connection gives the pre-release track a role beyond standard audio promotion. Based on the available reports, “STARSTRUCK” functions as both an advance song from the fourth mini album and a musical link to related narrative content scheduled between the single and the full album.

With “STARSTRUCK” now released on May 15, the next confirmed milestone in FIFTY FIFTY’s rollout is the June 1 release of “Imperfect-I’mperfect.” The available reporting establishes the single as a pre-release track, the album as the main comeback project, and the intervening scheduler content as part of a structured promotional sequence leading into the group’s fourth mini album.
