I think she'd be a good soloist, but I think she'd prefer to be in a group. And she clearly loves baking, so if she wasn't in Kara I'm sure that's what she'd be pursuing.
I started off liking Hara because of her giant pretty eyes, and Jiyoung too.. but when I went to KMF in 2010 and saw how cute Nicole was, I fell for her right away. ;~;
I'd pick Nicole - she's so much fun, I think she'd be nice to hang out with. It'd be fun to bake with her, baking is one of my hobbies and I know she loves it too.
Seungyeon would be fun too, though... we could both drink kahlua |D
