He said, "It was my first time as an MC so the more I held my mic, the more I shook.  That's why I tried to tense up my legs, but then my legs shook."

Kim Chang Ryul was understanding as he said, "There's something very burdensome about live broadcasts.  Delivering your lines can be nerve wracking and difficult."
