On October 27 episode of SBS' television show 'My Little Old Boy', Choi Jin Hyuk made a guest appearance.

The mothers responded, "Oh yes, of course. We've seen you kiss a lot of girls on TV. How are you so good at kissing though?"
Choi Jin Hyuk chuckled and said, "No, I really am not that great at it. Honestly, I'm not."
He continued, "It's probably as I just filmed a lot of kiss scenes. In one of the dramas I filmed in the past, I kissed at least one to two times in each episode."

Choi Jin Hyuk gave his honest answer to the question, "Well, yes. There were times when I had developed feelings for them. I mean, I'm a human being like everybody else."
The actor went on, "But that didn't happen all the time; sometimes, those feelings just didn't develop at all."
