She sure was! Before this dancing queen of After School stepped into the k-pop scene, Kahi was an experienced back-up dancer for many famous singers including Country Koko, Shin Jung Hwan and Tak Jae Hoon's old group. On the latest episode of Sang Sang Plus, members of After School, Shin Jung Hwan, and Tak Jae Hoon talked about Kahi's days as a back-up dancer. She was most recognized for performing alongside BoA for a long time. Kim Jong Min shared, "I knew Kahi since her back-up dancing days. She was the queen of back-up dancers." Some of you guys might be wondering why a gorgeous girl like Kahi who can rap and sing would stay as a back up dancer instead of becoming a singer. She explained, "Before my debut, I was crazy about dancing. That's why I turned down all the singing deals." It's a good thing that she changed her mind about singing because now she is providing major eye candy a great majority of the male population. On second thought, maybe it isn't such a good thing (for girls)...
