Se7en was blind sided with a question about his infamous massage parlor incident that occurred during his military service period.

On the October 13 episode of 'Happy Together,' Se7en was looking a little bit nervous, saying, "It's been 4-5 years. I worked and made it day by day."

One of the show hosts, Jun Hyun Moo, mentioned a letter of apology letter Se7en wrote after the incident, and Se7en responded, "I always felt sorry and repentant, but because I was in the military during that time, I did not have a chance to properly explain myself. Instead of defending myself, I wanted to apologize first." 

He continued, "I wanted to talk about deserting the place of duty, and I thought that I would have an opportunity to talk when I would start working again, but when the articles about my dating were released, I was confused. I wonder if I will have a chance to muster up courage and discuss this." 

When Jun Hyun Moo asked indirectly about the massage parlor controversy by saying, "Did you go in and do nothing else?" Se7en was flustered but replied, "yes." 

He then added, "I hope people don't misunderstand me with inaccurate information. I've suffered a lot."
