I do believe that only big companies can make idols from other countries having a lot of popularity and attention from everyone ( exc countries like japan, china, etc than common seen in Kpop). Look how Hanni from Newjeans getting much buzz on her debut compare to Hanbin from Tempest and Ahn from BeautyBox. I mean, everyone can see the difference between Lisa and Bambam popularity compare to Sorn from CLC and Prince from Ghost9.
Alex and Fatou as the first black idols in kpop didn't receive a lot of attention and hype. Many don't even know there are black idols in kpop. Their group unfortunately can be considered as flop and nugu. So, do you think it's possible for big companies debuting a black idols like they do to SEA idols? I'm sure it will get a lot of hype and support than when small company doing it. And probably they will become more common in kpop scene like how SEA idols are now even they're still not many of them.
Note: I'm not a native English speaker, so I'm sorry if the term of black idol sounds offensive or wrong.
