I feel like after seeing the awesome success other certain loop groups have had companies have started to debut more groups in hope of getting a sip of the international exposure and national hype that kpop has recently been getting. I feel like the members have also this mindset and when they ( the companies or members ( especially international members )) don’t achieve that almost instant fame they bail out . like cherry bullet my favourite gg I think 3 members left? And 2 were foreign . Tbh I don’t blame them. The industry is mentally and physically tolling and putting your all into a situation where it’s pointless and you believe you won’t reach your goal is tough. Especially away from family. That’s why I really admire big groups from originally small companies. Your chances of success are so low but never zero and that’s a mindset I admire.
