I know some PlayGirlz/Boys were confused as to who was who in the “Flashback” teaser so I jacked the breakdown below from lacksadaisical
Okay so after going through this entire teaser frame by frame about five million times, it’s still extremely difficult to figure out who is who, but it IS possible. One a side note, I really do agree with the majority and think that while the who dark effect is cool, I don’t want it to be in the full music video because I can’t see their gorgeous faces. Even though it probably will be anyway.
*Disclaimer*
The post is how I analyzed things and some of it may be wrong.

Jungah.
The hair of the girl dancing is parted down the middle, with bangs completely out of her face, those bangs go onto both sides of her head. Jungah and Raina are the only ones with hair like that (well Nana does, but she is blonde) and Jungah is the only one of those two that has short sleeves.

Juyeon.
I came to the conclusion that this torso rub/hair toss/on the floor dance move is Juyeon because she seems to have the shortest hair out of all the girls this time around. Plus, this person has no non-transparent sleeves/straps and so it must either be Juyeon, Lizzy, Uie, or Jungah. Juyeon is the only one whose hair would be short enough to be at that length while flipping.
What also gave her away was her posture. Jupal has a very stiff spine while she dances, her back is always straight.

Uie.
Its easy to tell who is Uie because she’s the one wearing the black outfit with the thickest straps, plus, those honey thighs are pretty much recognizable from anywhere.

Nana.
This doesn’t really need much of an explanation as its rather easy to see, Nana has very distinctive features that stand out an extreme amount in comparison to the other girls.

Lizzy.
Now, there has been some conflict over whether or not these scenes were Lizzy or Nana (obviously they’re one of the two since the person dancing is blonde). The reason I don’t think any of this is Nana is because Lizzy has a dirtier shade of blonde than Nana does, Nana is basically beach blonde, while Lizzy is still highlighted with a few touches of golden brown. Also, as much as I love Lizzy, Nana is a little bit less of an awkward dancer than she is. Nana would have flowed a little better in that last standing dance move. Also, upon further inspection, going frame by frame, the features of this girl are most definitely Lizzy.

E-young.
To be honest, I judged this by body type (E-young has a big-ish butt), but it very well be that the light was playing tricks on me when I thought that this person had long selves on both arms and that this is actually Uie. They had no Raina in this teaser, so it shouldn’t be very shocking to see that their is no Eyoung either (as unfortunate as that is because she is adorable).

Kaeun.
I was very surprised at how much of the new member I managed to see, she stood out with her one bare/one covered arm and tassels only on one side. It was obvious it was Kaeun whenever she appeared in the teaser. [lacksadaisical]




amazing analysis ! you are truly great playgirlz !
Now that I think about it…I think this might be a cut from their Intro (kinda like Let’s Step Up, Let’s Do It) and not the actual Flashback song
Oh! I never thought of that! haha I hope so!
After analysing the MV myself, I can confirm these:
“torso rub/hair toss/on the floor dance” is JungAh not Jooyeon
the U-ie part with the left hip sway is Kaeun
the Lizzy part where she extends her leg to the left is Nana &
the last standing dance move is actually U-ie
I screencapped the vid when the light illuminates them but i don’t know how to post pics here, came to this conclusions by seeing their faces
The person in the close up is not Jooyeon but E-young :OO
It’s Juyeon
E-young’s eyes and nose are sharper than Juyeon.
But look at her mouth :O Jooyeon’s upper lip isn’t like that! O.o
OMG! I was thinking the same! I thought it was E-Young but it seems is Jooyeon
