On December 24, Chef Yoon posted several photos on his Instagram with the caption, “2024 was tough but filled with memories. Goodbye! Next year will probably be tough too, right?”

Among the photos was a snapshot he took with Goo Hye Sun, which quickly drew attention. The two recently wrapped filming for an episode of MBC's 'Radio Star.'

In the photo, Yoon Nam No and Goo Hye Sun are seen posing closely together on the 'Radio Star' set, radiating an unexpected friendship.

The episode featuring their appearance is scheduled to air next month. In addition to Goo Hye Sun and Yoon Nam No, the show will also feature former baseball player Choo Shin Soo and actor Kwak Si Yang.

Meanwhile, Goo Hye Sun is set to share an amusing story on 'Radio Star' about attending university at the age of 40 and receiving attention from a younger student. She reportedly commented she was hit on by a college student and shared, “I was worried about his mother,” adding to the humor of the episode.
