Kwanghee appeared as Seo In Young's best friend and exposed what he knows about Seo In Young. During his little scoop on his diva friend, Kwanghee expressed deep empathy for the exhaustion Seo In Young experienced in her heyday and the void she felt during her hiatus. 

He explained, "There is no such thing as trending forever. There are always new faces and the people welcome them. Even so, they say, 'S/he is irrelevant,' and 'Isn't s/he old news?' When we hear that, we [celebrities] are hurt," spilling his honest feelings. 

Another guest that appeared as Seo In Young's best friend, Kang Kyun Sung, gave his viewpoint. He said, "Popularity is not worthy enough for us to chase. [Doing so] doesn't give us happiness."
