K-Will, 'President Joo' (played by Lee Deok Hwa), and 'Kyung Jae In' (played by Park Hyun Suk) had all humiliated Kang Woo (Eric) as they talked amongst themselves.�While the young Kang Woo was dancing, K-Will said, "There are lot of faces like that in Southeast Asia," indicating that Eric's face was too foreign-looking to make it in the business. Viewers responded well to the cameos, as they said, "I was happy to see K-Will, even for just a short time" and "Gun's performance wasn't bad!"
