JYP Subsidiary INNIT Introduces First OURBIRTHDAY Members Ahead of Debut Single

INNIT Entertainment, a subsidiary connected to JYP Entertainment, has started the public rollout for its upcoming girl group OURBIRTHDAY by revealing the act’s first three members. The announcement introduces Cho Hyejin, Baby, and Achiraya as part of a seven-member lineup, giving K-pop fans the first concrete look at a debut project that is now moving from name recognition into active pre-release promotion.

The reveal arrived through a teaser clip titled “ERROR 502: Bad Gateway”, a tech-themed phrase that signals the group may be leaning into a sharp, digital-forward visual concept for its opening campaign. While the full musical direction has not yet been disclosed, the naming of the teaser and the staggered member introductions suggest that INNIT is building a debut narrative rather than simply releasing profile images all at once.

Among the first names announced, Cho Hyejin may be the most immediately familiar to some viewers. She won the audition program THE DDANDDARA last year, making her inclusion a bridge between televised talent discovery and a formal idol debut. That background gives the group an early point of recognition, especially for fans who followed the audition format and are now watching how its winner transitions into a team setting.

First Members Set The Tone For A Seven-Member Lineup

Baby and Achiraya were also named in the first reveal, rounding out the initial trio. The decision to introduce only three of the seven members at this stage keeps attention on individual identities while leaving room for the remaining members to be unveiled through later updates. It is a familiar K-pop debut strategy: each reveal functions as both a profile moment and a reminder that the full group picture is still taking shape.

OURBIRTHDAY is scheduled to release the digital single “HUNGRY (Side A)” on July 22 at 6 p.m. KST. The title alone points to ambition and momentum, both common themes for rookie acts trying to make a clear first impression. The “Side A” framing also leaves open the possibility of a broader project structure, though INNIT has not yet detailed whether it will connect to additional releases.

The group’s arrival is notable because of its link to JYP Entertainment’s wider ecosystem. JYP has long been associated with high-profile girl group development, from earlier generation leaders to current global acts, so any new team emerging from a JYP-linked label is likely to draw extra scrutiny. That attention can be useful, but it also raises expectations: fans will look closely at vocal identity, performance style, member chemistry, and how clearly OURBIRTHDAY distinguishes itself from senior groups under the broader JYP umbrella.

A Debut Rollout Built Around Curiosity

The short lead time between the member reveal and the July 22 single makes the coming days especially important. Additional member introductions, concept photos, and possible audio or performance teasers will likely determine whether casual curiosity turns into broader pre-debut momentum. For a rookie group, early communication matters because it shapes the first set of talking points before the music is even released.

INNIT’s current approach appears focused on controlled disclosure. By naming three members first, referencing a stylized teaser title, and setting a firm release date, the company has given fans enough information to begin following the rollout without resolving every question immediately. That can help generate repeat attention, particularly in a crowded K-pop environment where new acts often compete for visibility days before they officially debut.

For now, the central facts are clear: OURBIRTHDAY will be a seven-member girl group; Cho Hyejin, Baby, and Achiraya are the first members confirmed; and “HUNGRY (Side A)” is due on July 22 at 6 p.m. KST. The next updates will show how the remaining lineup, concept language, and music previews come together as INNIT Entertainment prepares to introduce its new act to the wider K-pop audience.
