The PD explained, "At the time, he tried to send Min Guk off with a hand gesture but it didn't work too well. Upon watching that scene while monitoring, all of us got a big laugh."
He also revealed the staff's fondness for the 'Superman' kids and the families, by adding, "A PD and writer get assigned a fixed family. Because Sarang, Haru, and the twins have already been filming for over a year, the children and producers have established a strong bond. The children call the PD and writer 'aunt,' 'uncle,' or 'ahjusshi'... During breaks in between filming, sometimes they ask to be held. When the father can't care for the children by himself, the staff also watch over the children.
