Park Myung Soo confronted Jessica about their past hit duet "Naengmyeon".

On the latest episode of Park Myung Soo's YouTube series 'Hal Myung Soo', the variety star was surprised to see former Girls' Generation member featuring as a guest. After spotting her, he expressed, "Who is this?" Jessica then took off her mask and said, "I knew he would forget."

During their interview, Park Myung Soo asked Jessica, "You really hated doing 'Naengmyeon' in the past, didn't you?" She responded, "When did I dislike it? You shouldn't ask like that." He asked if Jessica noticed his mistakes, and she explained, "I saw everything from the side. On the stage, I have eyes on the back of my head. However, I was a rookie, so I had to do it exactly as it should've been."
