On April 13, DJ Park Myung Soo put on "Naengmyeon (Cold Noodles)" as the opening song on 'Park Myung Soo's Radio Show'. After listening to the track, he thought back to when he and Jessica performed for the first time together. 

He said, "This is something I sang with Jessica. At the time, Jessica treated me cooly. Back then, she was just a baby but now, she's completely a lady," thinking how fast time has passed since then. 

The two stars first sang "Naengmyeon" together back in 2009 during 'The Olympic Highway Duet Song Festival'. Before that, the song festival specials first started in 2007 with 'The Gangbyeon Expressway Gayo Festival'. Park Myung Soo confessed, "At the Gangbyeon Expressway, there were 3 people. I thought to myself back then, 'Do I really need to do this or not?'" 

He finished by saying, "As time goes, I really need to make a classic like ['Naengmyeon'] again. I'll work hard."
