The part where Wooyeon shakes her hand in a fist. I would like to share this because the only reason I figured this out is because of someone commenting saying "I HATE this part" under either a stage video or dance practice on YT. At first I thought, oh, well that's one way to see it. Only later, I realized they were doing it intentionally because the lyrics are "Pretending to be pretty or innocent, it's not fun at all, I hate obvious things". Just watch the timing of the moves and the lyrics. I think it is on purpose.
0:43 and 2:01
The part in the MV
The only reason this might not be on purpose is Wooyeon was 17 at the time but the choreographer may have intended the dance sexual regardless. I can't find who did the choreography, I could only find Purple was choreographed by Silvergun (YGX) so I assume they use outside people.
Here are all the comments under dance practice/choreography/stage videos I found that are related to this. Unfortunately I can't find the original comment that brought this to my awareness, but I remember the banana milkshake one.
(All the timestamps are referring to the same move)
Idk the hunter x hunter reference but I think it's talking about the same thing.
And by the way please do not delete this thread if it is too much and just alter the wording into something lighter like idk "inappropriate" or "weird" instead of sexual
