Everytime I see All Boys High I'm reminded that they sacrificed promoting Rooftop better to that drama while it was rising on charts at that moment. We were screaming FNC to do sth and get NFlying everywhere (like BraveBros did for BG) but they were just busy filming a webdrama

BraveGirls started going everywhere the moment they started to get attention and this helped them a lot to create even a bigger impact but N.Flying was nowhere to be seen while their song was rising. They started to promote days after rooftop hit #1 & dipped after their comeback

for tours aka direct cash, short term money : ) This is why I say management difference changes everything just look how Kwak Dongyeon's career is flourishing after he left FNC.
