Is she a good singer or rapper? (I'm asking because I don't know). Sometimes people complain about their faves not having enough lines but honestly, if they're not that great or others in the group are stronger, I'm not sure why that's a surprise.
I feel like the real question to ask is
Is she a significantly worse singer and dancer than the other Kep1er girls? No. Besides Chaehyun, who can sing in that group? And no, Youngeun is not even Liz level lmao. And Chaehyun gets less lines than Dayeon. Considering her popularity, Bahiyyih should at least get some of Dayeon’s lines. Her talent isn’t low enough to have only 5s of adlibs and most of her lines being chants. At least UP!, Wing Wing and Sugar Rush she was treated like a member of the group. But she isn’t the most shafted in the group. Yujin is tbh. She should be treated as the third top vocalist in the group but it looks like Dayeon took that spot. Mashiro and Yeseo aren’t that popular so then being shafted isn’t surprising.
