OURBIRTHDAY is moving toward its pre-debut with ‘HUNGRY (Side A),’ the first digital single from the new girl group project associated with JYP Entertainment. The release is scheduled for July 22, 2026, at 6 p.m. KST, placing the OURBIRTHDAY debut rollout in the final stretch after a sequence of official teaser materials and member reveals.1
The group’s early promotion has centered on Cho Hyejin, Baby, and Achiraya, whose group and individual concept photos were released through official SNS channels on July 16 and July 17.1 StarNews also reported the July 22 release time and identified the three as members of a multinational lineup.2
‘HUNGRY (Side A)’ Release Schedule

The key confirmed date is July 22, when ‘HUNGRY (Side A)’ is set to arrive as OURBIRTHDAY’s first digital single at 6 p.m. KST.2 The project had already been previewed earlier in July, beginning with a logo motion video posted to official SNS channels on July 2. That video used birthday-themed imagery including a cake, a clock, a birthday song, game sound effects, and a rapidly changing calendar to establish a bright and brisk project mood.3
JYP Entertainment said at that stage that further details related to the project would be revealed sequentially through official SNS channels.3 The following weeks matched that rollout pattern, moving from project branding to character assets, then to an introduction film and member-centered concept photos.

| July 22, 2026, 6 p.m. KST | Digital single | ‘HUNGRY (Side A)’ is scheduled for release.2 |
The title ‘HUNGRY (Side A)’ has been presented as the first digital single rather than a full album or physical release in the available source material. No tracklist beyond the title has been provided in the supplied reports.
Members Introduced Before Pre-Debut
The first three members named in the rollout are Cho Hyejin, Baby, and Achiraya. Sports Donga reported that Cho Hyejin was introduced with prior appearances on ‘Street Dance Girls Fighter 2’ and ‘The Ddanddara,’ while Baby and Achiraya were described through their respective strengths in dance and vocals.1
StarNews described Cho Hyejin as the final first-place finisher from KBS 2TV’s ‘The Ddanddara.’2 The same report identified Cho Hyejin, Baby, and Achiraya as part of a multinational member composition, although the supplied material does not provide further nationality details.
Soompi reported that INNIT Entertainment, a JYP subsidiary, is preparing to debut OURBIRTHDAY, and said Cho Hyejin, Baby, and Achiraya were introduced through the teaser clip ‘ERROR 502: Bad Gateway.’6 The available sources consistently place these three members at the center of the first public reveal stage for ‘HUNGRY (Side A).’
Teaser Rollout Builds the Group’s Setting
Before the member concept photos, OURBIRTHDAY released several project materials tied to its name and visual premise. NewsPim reported that three character moving posters began appearing through official SNS channels from July 11, introducing Cherisha, Grooblue, and Iyat. The characters were described with visuals recalling cherry cake, matcha cake, and blueberry cake, respectively.4
That report also stated that OURBIRTHDAY planned to present music and performances built around the idea of enjoying moments as if every day were a birthday.4 The birthday motif also appeared in the earlier logo motion video, which used cake and calendar imagery in connection with the project’s launch.3
The introduction film ‘ERROR 502: Bad Gateway’ added a more narrative layer. Dispatch reported that JYP released the film on YouTube on July 15, with a running time of about 1 minute and 11 seconds. The video showed members meeting in an unfamiliar space and blowing out candles on a cake, hinting at the group’s fictional world.5
Dispatch also described OURBIRTHDAY as the girl group JYP is presenting four years after NMIXX.5 A press-release quote included in the report asked viewers to “look forward to what story they will unfold.”5 The quote aligns with the broader teaser sequence, which has emphasized character imagery, a birthday-linked concept, and the introduction of members before the release of ‘HUNGRY (Side A).’

With the release date now set, the confirmed focus of the rollout is the July 22 arrival of ‘HUNGRY (Side A)’ at 6 p.m. KST. The pre-debut schedule has moved through branding, characters, an introduction film, and member concept photos, giving OURBIRTHDAY a defined launch path before its first digital single is released.
