On having Noh Hong Chul as her radio show co-host, Park Kyung Lim said, "He�was a mess. The director wrote up reports [on him]. Wasn't there a mistake made during a live broadcast?"

Noh Hong Chul added, "There were many. Every time I stood at the S Headquarters there was always something going wrong; because I rode a bike to work coming from Yoeuido, I used up all my strength and was tired. I ate something sweet but then because of constipation� a maknae writer had to host [in my place]."

The set laughed at Noh Hong Chul's story, as the maknae writer confirmed, "Because Noh Hong Chul had an urgent bathroom situation, while he stayed in the bathroom I took his place [as a radio host]."�
