Would you agree every big brand only want BTS and other Korean artist are just 2nd choice?

Well actually it's kind of interesting so I will write an example here.

Let's say those companies:

Adidas, Nike, Puma, Reebok, Fila

are in need of a brand ambassador and all decide to go with kpop artists

now only one of them can have BTS which means that there are 4 spots open

and in addition to that, you never know which tv commercial video will be better, as well as you don't know which clothes/shoes will be better.

And in another addition, all of those companies for us are "biggest brands" well known-worldwide but... all of them also are competing with each other, have different revenue, etc.

It's a too complex thing to just say that everyone wants BTS.
