Actress Song Ji Hyo and actor Lee Jong Suk showed skinship to each other.

In SBS "Running Man" aired today, Lee Jong Suk came out as one of the guests.

Song Ji Hyo and Lee Jong Suk had to carry out missions without other members noticing it. In the first game, they had to link arms. They linked arms while other members were focused on the game itself.

Their second one was to hold hands. This seemed hard with other members so close to them, but they once again successfully carried out the mission.

Even the forehead-kissing mission was sneakily done without other members noticing.

Internet users who saw this commented, "So cute!," "Is she over with Gary?," and "Gary is going to get jealous!"
