In the clip shown above, Kwanghee is strapped to a lie detector test. Yoo Jae Suk asks at the 0:20 mark, "In the past month, have you kissed anyone?" Kwanghee appears reluctant to answer, but finally says loudly, "Yes." The lie detector announces that Kwanghee told the truth, causing an uproar on the set.

HaHa immediately jumps up asking, "Is that person a celebrity?!" Yoo Jae Suk adds, "Just say 'yes' or 'no'!" Siwon throws in, "Answer honestly!" Seeing Kwanghee's hesitation, Park Myung Soo says, "Is kissing a bad thing?!" Meanwhile, Kwanghee shouts in protest, "Stop it, please!" and, "I'm going to call my manager!" 

Finally, Yoo Jae Suk brings order to the chaos by asking, "Is that person [you kissed] a celebrity?" Kwanghee replies, "No," and the lie detector agrees with his answer. HaHa, being HaHa, tries to keep going by asking, "Have you ever kissed a celebrity?!" but his attempts are shushed by Yoo Jae Suk. 

During the same episode, Kwanghee was asked about his previous statement that he wanted to go to SM. Kwanghee shared his regret in that statement, saying, "My [Star Empire] CEO monitored the episode. So I'm nervous."

When Yoo Jae Suk asked, "What did your CEO say?" Kwanghee answered honestly, "My CEO is really tied up right now," possibly referring to the Yewon and Lee Tae Im situation.
