When the reporter brought up his viral dance to "Boombastic" for a part of the drama's teaser, Park Bo Gum answered that he was actually embarrassed to be dancing like that in front of everyone. He said, "I practiced a lot by watching Kang Dong Won's dance clips. Honestly, I felt shy because I've never danced for so long during a filming. It was the help of the people on set that resulted in an awesome video." 

We thought the dance was really cute and would like to see more of it!
