Secret (Korean: 시크릿) (Subtitle: Are You a Good Person?) was a game-talk show featuring secrets of celebrities. Originally airing after Immortal Songs 2, the program faced difficulty when Immortal Songs 2 aired for too long, thus eating into the airtime of Secret. On one occasion, the program only aired for three minutes on July 23, 2011.[1]
Stars must play games and succeed to prevent a secret of theirs from being revealed by a friend.[2]
