GwakTube (real name Gwak Jun-bin) appeared flustered when he did not recognize Park Ji-hyun.

In the 31st episode of MBN variety show ″Jeon Hyun-moo Plan 3,″ which aired on May 15, Jeon Hyun-moo and GwakTube went on a food trip to Samcheok, Gangwon Province, and trot singer Park Ji-hyun appeared as a ″food friend.″

Before the food friend appeared on the show, Jeon Hyun-moo said that the person was ″an idol in the trot world″ and ″probably has the widest age range among trot singers I know (in terms of fans).″ GwakTube guessed, ″Lim Young Woong?″

When Park Ji-hyun appeared, GwakTube was surprised and momentarily could not remember her name. However, GwakTube revealed that he knew Park Ji-hyun’s name through ″I Live Alone.″ Jeon Hyun-moo joked, ″You almost emigrated. She has a lot of fans.″
