After School continued to show evidence of their hard work and dedication to pole dancing with a sighting of their wounds on 'Star King'.

Nana, who was wearing shorts at the time, especially caught the sympathetic eyes of viewers with the bruises on her legs that can be seen from a mile away. Boom asked, "Did you injure yourself while you were practicing?", and Nana simply replied, "Yes." Kang Ho Dong then joked, "I heard that the relationship between the After School members is not good", teasing with his explanation of Nana's bruises.

Nana explained, "The moves that we practiced involved landing with our knees. We learned it for about six months. We started learning the basics and kept practicing. So we have a lot of wounds over our whole body."

Leader Jung Ah shared, "Even our hands are peeled and calloused. More than any other exercise, it works out your whole body. I even formed abs that I didn't have before." 

After School effortlessly pulled off the intense pole dancing moves for title track, "First Love", proving that those six months of practice paid off!
