They had steam with AfterSchool but Ven Para destroyed them musically. Jiyoon leaving and her subsequent scandal (not her fault) also tarnished the group's reputation with overseas fans. Sales are still okay-ish but they're chained by mediocrity. IST despite having big financial backing from Kakao still failed to deliver. They only have themselves to blame while smaller agencies like S2 are making a killing with KIOF by tapping into Gen Z's conscience. It's either you innovate and change with the times or be left into dust.
