DinDin appears as a guest on ”First Commander”... ”I think I'm an elementary school student” = ”Kao Jung”

DinDin appeared as a guest on the elementary school mission. On the 11th, KBS2 variety show "Going, Coming, Lee Min JEONG" aired.
On the TV program, the first president (a person who is extremely popular among elementary school students), DinDin, was broadcast as a guest. On this day, the Jeong siblings chose the guest they were looking forward to for the elementary school mission.
DinDin commented, "You were waiting outside, but you came in early when you heard about 'RIIZE'. I listened to the guests that have come so far, and I heard that you were coming as an exclusive.
"No way," he said shyly. When asked why he became the first leader, DinDin replied, "I think he was an elementary school student. Because we are the same age.
When I was little, my neighbour had a senior friend named Haha.
The second and third generations are all Wonyoung. In fact, we are former members from the same school."
