AOA's ChoA appeared on the November 17 installment of KBS 2TV's 'Hello' and talked about her current concerns.

She stated, "We were preparing for our new song this time and it was a 'Cat Woman' concept, so you have to give off a cat-like vibe. �I watched the musical and even 'Animal Farm,' but it still feels hard, so I am still worrying about it."

This caused the other MCs to ask her to show how she mimics cats to see for themselves. She showed how to sit like a cat and make gestures with her hand as if it were a paw, causing Shin Dong Yup to say, "I don't know if it's similar, but it's nice to see," making everyone laugh. �
