MC Yoo Hee Yeol asked, "Were you ever embarrassed doing the 'crab dance' in your latest choreography?"

Hyorin said, "I'm always embarrassed. I didn't think I would get this much criticism. My confidence has greatly decreased and I've become dispirited."

Yoo Hee Yeol said, "My concern was whether your hip might go out like that."

Hyorin responded, "My hip is okay, but I have to hold myself up using my thigh muscles while wearing heels. When we were filming the MV, we filmed the group dancing scene the whole day, but my legs gave out and I couldn't stand.  I couldn't hold myself up and kept falling over."

Do you think the 'crab dance' suits the song?
