Actor Go Yoon-jung carries out an undercover operation for Park Myung-soo on MBC's variety show "Manito Club." The fourth episode, airing on February 22 at 6:05 PM, features an undercover gift mission with the theme "Handmade." This episode stars Jung Hae-in, Go Yoon-jung, Park Myung-soo, Hong Jin-kyung, and Kim Do-hoon.

In the pre-release video, Go Yoon-jung is seen embarking on the undercover mission for Park Myung-soo. The footage includes a scene where she waits in front of the Yeouido broadcasting station for Park Myung-soo's schedule to end while enjoying a jajangmyeon mukbang. Even during this, she immerses herself in the undercover mission, expressing concern by saying, "This is tough, what should I do? How did everyone else handle this?"

Go Yoon-jung revealed a "caricature bread box" she prepared herself. As an art school graduate, she carefully drew Park Myung-soo's face and his pet dog, Kara, attracting attention. She also created a heartwarming story by surprising the production team with a gift of Duzzonku (Dubai chewy cookies). When the production team responded, "This is our first time trying these," Go Yoon-jung smiled proudly and gave her share to Park Myung-soo. She said, "Duzzonku is love. I gave it all away."

Go Yoon-jung's undercover fashion also drew attention. She showcased a perfect "concealment fashion" by wrapping a scarf around her head. She revealed a cute twist by saying, "I can't see ahead, can I?" Later, a tense atmosphere was created as Park Myung-soo's arrival approached. Toward the end of the video, Park Myung-soo appeared, creating a thrilling moment about 10 meters apart. Go Yoon-jung was seen avoiding the spot and then approaching again, continuing the suspenseful operation.

The fourth episode of "Manito Club" will air on February 22 at 6:05 PM.
