OURBIRTHDAY - The 1st Digital Single: HUNGRY (Side A) (Concept Photo - Individual)

The members: Cho Hyejin 🇰🇷 Baby 🇹🇼 Achiraya 🇹🇭 Cho Hyejin finshed #5 in The Entertainer and thus was supposed to be a member of the cancelled DDDD25. The remaining two were previously unknown. Supposedly, Baby's full first name is Angelababy, I imagine she was named after the Chinese actress who has that stage name. Maybe JYP/Innit wanted to avoid problems with the name, but shortening it to Baby instead of to Angela is a little bit unusual 😅 I guess it does fit with everything being about birthdays. Also supposedly (yes, most things about this group are in rumor phase right now) "Side A" is a sub-unit, and the full group has more members; with rumors swirling around: Yu (also from the ill-fated DDDD25), Kim Byeori (The Entertainer contestant) and Hyewon (R U Next contestant).

Is the trend shifting towards having less members?

they’re gonna be 7

Mostly rumors 😭 But also Naver : OurBirthday marks JYP Entertainment’s first new girl group since the debut of Nmixx in 2022. JYP is expected to roll out more member introductions in the coming weeks, with only three out of seven members revealed as of Thursday.

From what it seems, this is just the first unit of a bigger group (potentially 7 members, but not confirmed). They seem to be called Side A (their debut digital single will be called Hungry (Side A), so I guess there will be a Side B and potentially Side C as well.
