it seems that NCT dream had an Impact on NCT 127

lmao this is happening because they released a new song, not because Dream had an impact on them. Dream's comeback happened almost a month ago.

I mean I am sure with every CB they will have more fans checking the NCT brand especially when it does well but it's weird crediting Dream for that specifically when there is nothing suggesting it. +127 just released a song so that's probably 99% of the reason why.

127 always did as good or better than dream digitally, it's their kfanbase working for it. Public reception will me more accurate to tell when it's their official comeback
