JYP Entertainment's subsidiary INNIT Entertainment is building anticipation for an upcoming girl group debut. OURBIRTHDAY, a seven-member group, has just introduced its first three members through a teaser clip titled "ERROR 502: Bad Gateway."

The revealed members are Cho Hyejin, Baby, and Achiraya. Hyejin brings recognition from winning the audition program "THE DDANDDARA" last year, giving her some industry visibility heading into the debut. The teaser's title—a playful reference to a web error—suggests the group might lean into a tech or digital concept.

With three members introduced and four more still to come, INNIT Entertainment is clearly staggering the reveal process to maintain momentum as the debut approaches. This strategy keeps fans engaged during the pre-debut period and gives each member individual attention as they're introduced.

OURBIRTHDAY marks another new group under the JYP umbrella, which has been actively building its roster beyond the company's main label. INNIT Entertainment, as a subsidiary, gives JYP the flexibility to develop different sounds and concepts while maintaining oversight of the company's training and debut pipeline.

The group's name itself—OURBIRTHDAY—suggests a concept centered around celebration and unity. The error-themed teaser clip hints that the group may play with digital or glitch aesthetics in their branding, a approach that resonates with younger audiences familiar with internet culture.

Fans can expect the remaining four members to be revealed over the coming weeks or months as the debut date draws closer. Given INNIT Entertainment's connection to JYP's resources and expertise, the group will likely benefit from the company's established production quality and promotional infrastructure.

More details about the group's debut date, music style, and the identities of the remaining members are expected to follow as the pre-debut campaign continues.
