Ji Suk-jin didn't know Nickname of the Kobuk left Yu-Jeong.
On SBS's "Running Man," which aired on April 4, the group Brave Girls (Min-young Yu-Jeong Eunji Yuna), who wrote the reverse running myth, appeared.
"Brave Girls is the first to appear in the variety entertainment program," said Yoo Jae-Suk. The members said, "The entertainment we wanted to do most is Running Man'."
Ji Suk-jin, who heard this, said, "Honestly, we missed you so much, I'll shake your hand."
Among them, Yang Se-chan said, "I asked me what the 'kook left' was and told me that it was 'twisting the Leg like a kobugi'. I do not know anything and pretend to know what. "
