C9 Entertainment’s new girl group Good Day has now introduced three more members ahead of their debut. Meet Bomin, Jiwon, and Lucky below!

If it’s true that the number of “likes” on each photo reveals the members’ birthdates, then Bomin was born on September 24, 2001, Jiwon’s birthdate is April 1, 1999, and Lucky was born on November 3, 2001.


C9 Entertainment has now officially begun the lead-up to the debut of their new girl group!

On July 7 at midnight KST, C9 Entertainment revealed that their new ten-member girl group (formerly simply referred to as C9 Girls) will be called Good Day by launching a Twitter account for the group.

Good Day has shared a look at two of their members through their first photos, introducing members Genie and Nayoon.

The two images include the text “Morning” and the number “0831,” hinting at a possible debut with a release of that name on August 31.

The number of “likes” on each of the Instagram-styled photos may also be a clue about the members, as Genie’s “19,970,107” may mean her birthdate is January 7, 1997, and Nayoon’s reads “19,990,330,” possibly hinting at a birthdate of March 30, 1999.

C9 Entertainment previously also released a timetable for the debut of their new girl group, which announced that more photos will be coming up on July 11, 12, and 13.
