During the skit, Song Joong Ki kisses her on the cheek making the audience go wild. The comedian recalled the heart-fluttering moment, saying, "The audience loved but so did I." Shin Bora added, "When I got off stage, I got in so much trouble by the director, saying how I acted so selfishly," laughing away.
