Park Seoyeon has become a focus of attention around ABD’s first girl group after new teaser films from the HYBE Music Group label prompted renewed reports about the possible TUIDE lineup. The connection remains reported rather than officially confirmed: available source material says Park Seoyeon may be among the debut members, while ABD has only confirmed that some members of its upcoming girl group appeared in the films.12
ABD opened its official website and social media channels on May 26 and released six short films presenting the label’s brand direction. OSEN reported that the films marked the first appearance of some members of ABD’s first girl group, which is planned to debut in the second half of 2026.1
Park Seoyeon Linked to Reported TUIDE Lineup

The Park Seoyeon discussion centers on reports that identify her as TWICE Jihyo’s younger sister and suggest she may be part of ABD’s new girl group. NOWnews reported that attention grew after a teaser showed a ponytailed member, while also noting that the group name TUIDE has been reported in connection with ABD’s upcoming girl group.2
The same report also mentioned Park Seah as another reported name in the lineup, describing her as a former child model and actress.2 However, the available official information from ABD and HYBE does not confirm a final member list, individual member names, or a finalized public debut roster. The clearest confirmed point is narrower: ABD has released short films that include some members of the girl group scheduled for later in 2026.13
That distinction is important for the TUIDE Seoyeon topic. The public discussion is being driven by reported identifications and teaser interpretation, not by a formal member profile rollout. ABD’s own confirmed activity so far is the launch of its official channels and the release of brand films, while media reports are separately connecting Park Seoyeon and the reported TUIDE name to the project.
What ABD Has Officially Revealed
ABD is HYBE Music Group’s new girl-group-focused label. OSEN reported that the label name comes from “A Bold Dream,” and that Han Sung Soo is serving as master professional for the first group.1 Korea JoongAng Daily reported earlier in May that HYBE would debut a girl group under the newly established ABD in the latter half of 2026, with No Ji-won leading the label and Han Sung-soo directing the upcoming group.4
Soompi reported that HYBE announced ABD on May 8 as a new label specializing in girl group production, with its first girl group set for the second half of 2026. The report named Han Sung Soo as the executive producer overseeing music, concept, and performances.5
HYBE described ABD as part of its multi-label strategy, and the company said, “Through this new girl group, we will introduce new musical experiments and concepts.”5 That official positioning gives the project a broader corporate context, but it does not settle the specific lineup speculation surrounding Park Seoyeon.
The May 26 videos appear to be designed as brand-forward teasers rather than member introduction clips. NewsPim reported that the six short films were released through ABD’s website and social channels, and that they include scenes tied to the label’s stated focus on the joy of music.3 Sports Kyunghyang described one visual sequence as showing three girls dancing in shoes marked with the letters A, B, and D, with the label’s name used as part of the visual motif.6
Why the Seoyeon Reports Are Being Watched
The attention around Park Seoyeon is partly tied to her reported family connection to TWICE member Jihyo. Because Jihyo is a well-known third-generation K-pop idol, reports that her younger sister may debut through a HYBE-affiliated label have drawn wider interest beyond the usual pre-debut teaser cycle.2
Still, the available facts support a cautious reading. ABD has confirmed the label launch, the six short films, the presence of some members in those films, and a second-half 2026 debut plan. Reports have connected Park Seoyeon to the possible lineup and have also linked the name TUIDE to the group, but the provided sources do not include an official ABD announcement naming Park Seoyeon as a member.12
The same applies to the group name. NOWnews noted that TUIDE has been reported in connection with ABD’s new girl group, but the source material does not show an official naming announcement from ABD or HYBE.2 Until such an announcement is made, TUIDE should be treated as a reported name rather than a confirmed official debut name.

For now, Park Seoyeon’s reported link to TUIDE remains one of the main points of public interest following ABD’s teaser rollout. The confirmed story is that ABD, a new HYBE Music Group label focused on girl groups, has begun introducing its brand and has shown some members of a girl group planned for the second half of 2026; the specific claims around Park Seoyeon and the TUIDE name remain based on media reports rather than a finalized official lineup announcement.
