This year was his 20th anniversary.  "Even after the disbandment, I mistakenly believed that 1/5 of H.O.T's popularity was mine," he revealed.  "But it took two years for me to realize that was not true."

When asked why he's been so active as a singer and actor in China, Kangta said, "I wanted to go through trial and error to create a sort of manual for my juniors."  When MC Yoo Hee Yeol asked about his own possibility to break into the Chinese market, Kangta hesitated, making everyone laugh.

The singer also said on the show, "There are my initials and a heart on the wall at a restaurant I had gone to often with my girlfriend."
