On January 26 Lee Kwang Soo put a picture on his Twitter and wrote, “My friend Joong Ki used to be this kind of person. He still is like this.” He tweeted again, “I swear he’s going to be like this in the future too. PS. A sudden nostalgic Tweet.”
In the pictures, Lee Kwang Soo, Song Joong Ki, and singer Kim Jong Gook posed together for a friendly picture. In the last picture, the two actors comically wrap their arms and legs around Kim Jong Gook who grins broadly.
Netizens who saw this picture commented, “I am so jealous of how close Lee Kwang Soo is to Song Joong Ki”, “Kwang Soo is sentimenta”, and “Running Man friendship forever.”
