The first moment is when their faces are full of Jjajangmyeon in episode 323 of Running Man. At that time, they were given a mission and a challenge, the challenge was that they had to finish a dish of jjajangmyeon. In the first round, the one who had to eat jjajangmyeon first was Lee Kwang-soo. He was being fed by Song Ji-hyo with her eyes closed. Then when it was Song Ji-hyo’s turn, Lee Kwang-soo didn’t feed her properly and filled her face with jjajangmyeon.
Another exciting moment is when they were fighting. In this episode, their stomachs are covered with a pillow or something round, so that their stomachs look like sumo fighters’. At first, Lee Kwang Soo succeeded in making Song Ji-hyo fall by being pushed by his big body, but she managed to stand up again. Then, Song Ji-hyo didn’t want to lose, so she took revenge. To make Lee Kwang-soo fall, she didn’t push him, but pulled his hair and then lowered him.
In episode 168, “Submission Giraffe”, Song Ji-hyo eagerly pushed, rolled, kicked, pinched Lee Kwang-soo, who pretended to be a giraffe at the time, just to win the mission by taking notes from him. Lee Kwang-soo’s face looked like he was begging Song Ji-hyo, while she eagerly and mercilessly beat him.
It’s typical of siblings to take a ton of selfies together, and the same goes for the ‘KwangMong’ siblings as well. In episode 186, Song Ji-hyo and Lee Kwang-soo got a selfie disease. They adorably spent a very long time taking plenty of selfies, with a vast variety of poses. This moment is genuinely interesting and these siblings look very cute.
