Choiza looked uneasy when the topic of his girlfriend, Sulli, was raised during Dynamic Duo's appearance on 'Healing Camp' this December 28.  

One participant said on the show, "I had a severe fight with my girlfriend, and I felt that I shouldn't lose her, so I went on my knees.  She didn't say anything for an hour... in the end, she said that she was angry and left.  I got up to stop her from leaving, but your feet don't uncurl if you're on your knees for too long."

Kim Je Dong then said to Choiza, "While you listened to his story, you had a frown on and kept nodding your head.  Why did you do that?"  Getting nervous, Choiza replied, "I could empathize with his story.  I thought that it must have been very hard for him."

Seo Jang Hoon then asked out of the blue, "Did you experience going on your knees recently?"  Choiza instantly turned red and was unable to gather his wits, making everybody laugh as they watched him sweat.

Finally, he said, "When a man and woman are dating, there are times you need to placate them.  I'm the type who begs [for forgiveness] very casually."  Seeing Gaeko rub his palms together, Choiza added, "I'm the type that doesn't cause situations in which I have to go on my knees and I apologize right away."

When Jessi was asked if she ever saw a guy get on his knees for her, she replied, "Yes. That's because he did something he deserved to be punished for.  However, he did not go on his knees because he cheated on me."
