In my HUMBLE and BRAZILIAN opinion Growl is actually HUGE even ww at that time. I knew about Growl first then about kpop. It literally appeared some times in my national TV talking about how "this boy group called EXO are doing wonders and collecting a bunch of fans in Brazil and latam etc" so when people try to downplay it success I'm always like:
Bc think... If it was this successful outside SK, imagine in SK when they were literally blowing up.
