I mentionned HyunA-sshi before. BUT, to not repeat myself, I'll say someone else :)

Choi Sooyoung-sshi from Girls' Generation (SNSD)

She's really beautiful.

She has good values from what I've seen.

I always wanted a cool looking icey unnie (older sister).

She's a wonderful dancer. I wanted a sister to dance with.

She's fashionable.
