Say farewell to the beloved triplets and their awesome parents on 'Superman is Back'! Yesterday's episode was the final one for the family.

In an interview with the production crew, Song Il Kook said, "I could hardly believe it during the first filming. �I worried about whether I could pull this off in the end. �I gained confidence after trying it once. �From then on, I thought about what to do and was happy.

"It wasn't easy going around with my children. �It was hard, but I assure you they are the best presents in my life. �There were a lot of happy memories for me personally, but there were also people who saw the broadcasts, got inspired, and had their own children."
