During the most recent episode of 'Running Man', the 'Monday Couple' (Song Ji Hyo and Gary) teased fans with an unexpected hug.

During the "train survival" mission, the 'Running Man' members had to play a game where they had to group together to match the�random number a staff member shouted. The members participating in this round were Song Ji Hyo, Gary, Yoo Jae Suk, Ji Sung (special guest), and HaHa.

When the staff member�called out "2", Gary and Ji Hyo, without hesitation, went straight for each other and ended up in an embrace, while Yoo Jae Suk and Ji Sung chose one another. This left HaHa to be the odd one out, and thus, was eliminated from the train survival segment. Noticing Ji Hyo and Gary immediately grabbing for one another, Yoo Jae Suk commented, "You two always choose each other at times like this."

To this Gary stated, "There is only one person I need to seek out," causing everyone including Ji Hyo to laugh.

Later on in the actual "race" portion of the show, Gary was also seen trying to protect Ji Hyo from the others at times, once again leaving viewers longing for the return of the Monday Couple.

Viewers commented, "The reunion of the Monday Couple?", "I want to see the Monday Couple together again", and "The Monday Couple is what makes 'Running Man' fun."
