1st about the singing while dancing thing....
My answer would be Itzy...
Aespa's choreography is not difficult if you compare it with Itzy's choreography...
But itzy sings live all the time where aespa doesn't...
And about the perfection thing ,, if you see aespa's performance of lip syncing it's no where near being perfect.... Like they don't even do good with lip syncing.... They not only don't sing live but they don't even try to lip sync perfectly....
And don't talk about lee so min , he is a person who thinks lip syncing is a gener
And companies will give priorities to beauty than talent till people are good with it....
Like if you ask a fan about who is their fav group and why.. The most common and typical answer would be ( X is my fav and they are my fav because they are handsome/beautiful, pretty or cute...not because they are talented )
