The actor further added, "Right before the live broadcast Kim So Yeon told me, 'I don't know how this will turn out so don't run off.' So I thought, 'She must be up to something.' And what happened afterwards is exactly as you saw it. Kim So Yeon grabbed my head and kissed me." 

When asked how he felt to be kissed on a live stage in front of all those people, Kwak Si Yang answered, "I wondered if we really kissed. It felt a little surreal. Rather than thinking about the kiss, I felt more relieved that we were able to finish the performance without any problems. As you know, Kim So Yeon and I can't really dance. How many times do you think we practiced? We kept telling ourselves, 'Let's try not to get the choreography or the lyrics wrong,' so when we thought about how the performance was done and over with, I think we were able to relax. We weren't talking about the kiss but just happy that we did well [on stage]."
