So much similarity with AOA. Two main vocals Haeyoon and Bora. Bora is considered to be Choa while Haeyoon is Yuna. The company prioritize a main vocal girl despite lacking in height and/or visual which is nice. For visual, it’s Jiwon. But unlike Seolhyun, Jiwon is more of a performer than an idol trying to breakthrough acting, you can see her determination whenever performing. As for back up visuals, like Hyejeong, there’s May and Yuju. Sometimes they’ll get noticed here and there, but they won’t be the face. Lastly is the leader position Mirae, like Jimin. What differs them is dance and rap. AOA has a terrific rapper and sub, while CB only does well in sub rap. If Ahyeong debuted, she could contribute so much more. As for dance, it should be Dohwa but she’s more lead than main while CB were never really in the spotlight so Remi didn’t showcase much.
