WJSN sub-units:
CHOCOME: Soobin, Luda, Yeoreum, Dayoung
The Black: Seola, Exy, Bona, Eunseo
only two left are: Dawon, Yeonjung
this made me wonder if maybe it was all along planned by Starship?
Now hear me out...
Dawon is '97, and Yeonjung is '99
Dawon is known for being considerate, well mannered, she takes care of her members, and even cleans after them.
Yeonjung is maknae of the group, and former SM trainee.
What's interesting here is that Starship left main vocalists out from debuting sub-units...
Isn't it strange? Now about visuals, they are both very pretty, according to kpop profiles Dawon is 167cm, and Yeonjung is 168 cm. Which suggests they would "fit" well a group with Wonyoung, and Yujin. Dawon would be that experienced one, just as Eunbi was in IZ*ONE. In addition to that Dawon knows a lot about staying fit in a healthy way, she swims, does pilates, and conditioning workouts. As for Yeonjung well she was in IOI, and even as WJSN's maknae she always speaks whatever she wants, and she is known for being goofy, and doing fun things, like a mood-maker.
I say that unless Starship has some 5-6 talented girls in the dungeon then Dawon and Yeonjung would be a perfect fit for the group. Also I expect this new group to have at least 7-9 members, they will want to go with bigger group for sure.
