In the most recent episode of Running Man on SBS that aired on May 11, unexpected chemistry blossomed between Yoo Seung Ho and Ji Ye Eun as they were paired up as a "one-day couple" for the "Territory Marking of Killers" race. Guest appearances by actors Son Ho Jun and Yoo Seung Ho added to the excitement of the show.

The banter between the cast members was playful and entertaining. During a car ride, Ji Suk Jin made a joke about Ji Ye Eun's weight loss, to which she responded in jest. Yoo Seung Ho complimented Ji Ye Eun's beauty, causing laughter among everyone. Their interactions continued throughout the mission, with Ji expressing her fondness for Seung Ho, leading to more laughter.

In another segment, Ji Ye Eun humorously expressed disappointment when Yoo couldn't eat tteokbokki. Their playful exchanges continued, with Ji affectionately calling Yoo cute and feeding him the food herself, sparking jealousy from the others in a lighthearted manner.

The playful dynamic extended to a moment where Ji challenged Yoo, jokingly stating that if he ate a certain food, they would be officially dating. The cast members joined in on the fun, with Kim Jong Kook suggesting a short-lived relationship. Despite this, Yoo went along with the joke, solidifying their "relationship" for the day.

As the episode unfolded, humorous exchanges continued, with Ji claiming a seat next to Yoo and jokingly referring to it as her boyfriend's seat. This led to more laughter from the cast members and playful banter among them.

In the end, the "Grasshopper Team" emerged victorious, with Yoo Seung Ho winning his first game on his third appearance on the show. Although he avoided the punishment, he couldn't resist teasing Ji Ye Eun, which led to her getting soaked by Son Ho Jun's water gun. Despite trying to help clean her face, Yoo couldn't contain his laughter.
