>>45530659Bae probably has been dancing and keeping herself fit ever since her highschool days, that's why she got the experience moving her body with great proficiency, and even choreographed her own solo performance, so of course she would look better dancing side by side with Gura.
The only acceptable argument to OP is still Gura didn't have to be the best performer, she never had to be at that level on stage because it's too much effort with too little gain for her so far.
Bae, on the other hand, had to prove herself at least to the corpo and nips and probably the gooks she's been cultivating, so she can get a chance for the spot in future 3DLives, because she's a performer who wants to perform. And that's pretty much it, she doesn't expect to get more from it no matter how good she is on stage, because we all know the majority of EN viewers don't give a single fuck about the girls' idol performance, they just want their entertainment onahole. Even though this board is plagued with schizophrenia and faggotry you would find the random anon on a horny thread to care more about their performance than the average EN viewer.
Just not this guy
