During the recording for upcoming episode, Song Il Kook shared, "My wife gave me this mission... First off, I have to get through the 48 hours... I guess she thinks I won't survive the 48 hours," and showed his confidence about getting through it without a hitch. But that confidence was put to the test when he took his triplets to the park, who gave their dad a handful to take care of. Dae Han played like a fish meeting water while Min Guk flashed his smile and aegyo upon seeing the fountain, and Man Se took off to run around the park.

Song Il Kook also shared the highs and lows of raising triplets, "Because they're triplets, it's three times the difficulty but it's also three times the joy."

Welcome Song Il Kook's clan on 'Superman is Back' this Sunday!
