Actor Lee Dong Wook seems to be excited about the choreography for Orange Caramel's song "My Copycat." 

The cast of SBS's Roommate put on their dancing shoes and put their moves to the test with the help of Nana on the August 24th episode of the show.

For the dance party, Orange Caramel's "My Copycat" got everyone up and dancing with its fun beat.

The choreography was taught by Nana and all the roommates did their best to master the dance moves. They started jumping around the room having a good time.

However, when everyone else stopped, Lee Dong Wook was still dancing around and doing the hand moves, making everyone laugh. 

Do you think that Lee Dong Wook really looks cute while dancing Orange Caramel's "My Copycat"?
