Just from that, she def gonna be one of the weaker loona members.
I hope she proves you wrong when she debuts (I don't mean that to sound rude). I saw a video of her singing and dancing, but I'm not 100% sure if it's her, since my comment is based on that video, I'm not sure about what I'm saying either. But if she's the girl of the video, I think she'll probably be the main vocal of the third sub-unit. I saw in her the potential to improve and be the main singer of LOONA. Personally, I don't like Yves visuals that much, but if she is a good singer, I know that in that moment she'll become my bias, because I have a thing for main vocalists hahaha.
