Haven't they learned their lesson already? Previous attempts has failed big times. They need wrap around their heads and realized this does not work in Vietnam....
I think that they feel they do it better or something? I honestly don't understand it either. People need to just stick to what works for them and let music flow and build naturally.
a bit off topic but it's sick what kdrama and kpop is doing to the Vietnamese youth. Literally 50% of Viet girls I know are obsessed with Korean guys.
