Actor Cha Tae Hyun appeared on MBC's 'Radio Star' on April 27, where he talked about his wife.

He said, "My wife really liked Park Bo Gum while watching 'Reply 1988.'  However, once 'Descendants of the Sun' started, she immediately changed to Song Joong Ki.  It's been a while since I saw my wife's feelings change so quickly.  However, the time it took her to change was too short.  It was to the point even I was fascinated and shocked by it.  To make matters even worse, even the neighborhood women around her went, 'Oh my.  She changed so quickly, what's going to happen to Park Bo Gum?' and worried about him," making everyone laugh.

He continued, "There was a time when Song Joong Ki came near my house.  I was drinking with my wife, and he said that he was with Chang Suk so we should meet up with them after which the whole area went crazy.  My wife contacted everyone and got responses like, 'Did you save a country?' 'I have to go there,' and more messages went flying around.  From my point of view, it was so funny."
