I thought they debuted in September? whatBoyStory hasn't debuted yet, but both did fight over debuting the first Kpop group with no Korean members
NCT is under SM, we all know that in a few years, every company will try to do the same thing as them, just like they did with other groups.
They just let SM take the blows at first and wait till it's successful
That really seems to be the case, but even with their failures, SM still manages to make those groups into money makers eg. SJ and EXO lol
