On the most recent broadcast of�SBS' 'Running Man', the cast and guests competed around a 'royal family concept'.

Leessang's Gary was chosen to play FD Ko Dong Wan's second son, and then the PD told�Song Ji Hyo that she was to be the second son's wife.

When Song Ji Hyo heard this, she exclaimed, "We're divorced." HaHa responded, "Our family is broken because of the second son," while Gary replied, "Why is it like this? We can just get together again!" Song Ji Hyo and Gary have been affectionately dubbed as the "Monday Couple" by viewers as well as other castmates due to their unique chemistry on the program.

Viewers commented, "Song Ji Hyo's complaint was cute", "Song Ji Hyo's complaint... She must be in a difficult position because she has a boyfriend", and "I miss the Monday Couple".
