They were rising from 2020 due to wannabe and rtk really gave them a boost cause a lot of people didn't like that they were eliminated, so we saw pretty solid numbers with one, pump it up and especially burn it/ra pam pam. And Bomin was also a rising star being the host on Music Bank for a year and being on A-teen. I think Woollim sabotaged them with their japanese releases, I have a feeling they wanted Golcha to debut in Japan (which there was no need for) so they rushed their Korean comeback Ddara. I really like ddara but it came at such a rushed time. It really should've been a big celebratory moment for Daeyeol especially. I think their lack of Korean activites in 2022 is what finally burnt them off.
But the lack of activites have been happening with Woollim groups, there haven't been many Drippin and Rocket Punch when they desperately need the support. Golcha are quite lucky to have already built up a solid fanbase. Eunbi's the only act keeping the company afloat and even her comebacks are few and in between.
