The enduring rumors of a romantic relationship between Kim Jong Kook and Song Ji Hyo, known as the "Kkook-mong Couple" on the TV show "Running Man," have resurfaced.

In the upcoming episode airing on April 20th, the "Running Man" cast will be engrossed in a mission where they take on the roles of enthusiastic merchants. The task in the recent recording involved a "Merchant War: Live to Earn" competition where the members acted as part of the "Running Merchant Association," aiming to buy specified items and sell them for a profit.

A standout moment during the mission was when Song Ji Hyo affectionately called Kim Jong Kook "yeobo" (a term of endearment in Korean), causing a surprised reaction from Kim Jong Kook. This incident sparked curiosity among the other members about the nature of their relationship. Fans are now speculating about a resurgence of the "Kkook-mong Couple" and the true meaning behind Song Ji Hyo's use of "yeobo."

The "Merchant War: Live to Earn" challenge, promising both romantic moments and personal gains, will be featured on the April 20th episode of "Running Man" at 6:10 PM KST.
