When you talk about Kpop survival show winners, there a lot of big names over the years.
The first names that come up, all the Produce winners such as Somi, Daniel, Wonyoung, Yohan. Then there's Ryujin from Mixnine, Jungwon in I-LAND, or even Jisun in Idol School. But it seems like Chaehyun from Kep1er has no star power, or presence at all.
I'm not gonna talk about Produce winners, because they're on another level, but at least even Jisun from fromis_9 has been on variety shows, like Baek Jong-won's show or been on web-shows here or there. And Idol School has arguably way less hype than Girls Planet 999.
What went wrong for Mnet?
