The tvN special 'Reply Through Song 1994' aired on January 31 and featured some fun times with the cast members as well as the MCs.

On this day, MC Shin Bong Sun saw an opportunity and asked Yoo Yun Suk if the two could reenact his kiss scene with Go Ara in drama 'Reply 1994.'  He first asked, "Do I really have to?" then went to the front of the stage with Shin Bong Sun.  

Known for his bad boy tendency of grabbing a person by the back of the neck when initiating skin ship, Yoo Yun suk said, "I do not grab the shoulders when I do a kiss scene.  If anything, when I make contact..." He then grabbed the back of Shin Bong Sun's neck and went in for the "kiss."
