The long-standing "Kkook-mong Couple" rumors surrounding Kim Jong Kook and Song Ji Hyo on SBS's "Running Man" have been reignited!

In the upcoming episode airing on April 20th, viewers will witness the "Running Man" members fully immersed in a mission as enthusiastic merchants.

The recent recording featured a "Merchant War: Live to Earn" race, where the members transformed into "Running Merchant Association" members tasked with purchasing requested items and reselling them for the highest possible profit. 

During the missions, Song Ji Hyo naturally referred to Kim Jong Kook as "yeobo" (honey/darling in Korean), leaving Kim Jong Kook visibly flustered. The other members in the car reportedly erupted with excitement, questioning the nature of their relationship. This moment has fans wondering if the "Kkook-mong Couple," whose chemistry has been somewhat overshadowed by their "family-like" dynamic recently, is making a comeback, and what Song Ji Hyo's use of "yeobo" truly implies.

The "Merchant War: Live to Earn" race, promising both romantic sparks and personal gains, will be revealed on the April 20th broadcast of "Running Man" at 6:10 PM KST.
