Kahi spoke up about the time when she used to be�BoA's back up dancer and the creation of After School on the May 6 episode of�Mnet's 'Beatles Code 3D'.

On the show, past photos of her as BoA's back up dancer were revealed. �Kahi responded with some signs of embarrassment, "I think I was about 23-years-old. �I was ugly."

She said, "I became known as 'BoA's dancer' while standing on stage with BoA. �While BoA was preparing for her 'Valenti' stage, the Japanese dancers were showing the Korean dancers the moves, but one Korean dancer was lacking; hence, they told me to come and help with the practice because they needed more people. �I ended up working with BoA for three years."

Moving on to the subject of After School, MC Shin Dong Yup�said, "I heard that you and your CEO worked really hard together to create After School."

She said, "While I was promoting in [previous group] S-Blush, Bekah was a trainee. Bekah was so sexy that the CEO strongly recommended her and brought her from Hawaii. Afterwards, we were introduced to and chose Jung Ah. �Then we gathered Jooyeon and So Young for five (members)."

Shin Dong Yup asked, "Were you so affectionate that you made them assemble in the bathroom for important meetings?" �Kahi replied, "No. �Rather, I'm the type who says what I need to right then before going to the bathroom to think, 'Was I too harsh?' and cry."
