its been 4 years people are not going to change any more. Kpop in Korea especially is a solo stan deal NCT messes with that at its core. Expecting folks not already captured to become interested is crazy the amount of work is too high. Remember kpop is a diversion, something to distract from life people do not want to put that much effort into it. And except for a very few none do as a rule.
Its like me with loona / dreamcatcher there is just to much crap to get to know to even start to care. I would have to be Super invested to want to jump over that bar.
