Red Velvet's Seulgi busted some killers moves on 'Cool Kids'.

On the latest episode, not only did Seulgi talk about her unique facial features but also captured everyone's attention with her crisp dance moves. After discussing the pain that female idols must go through to dance in heels, Seulgi showed an example of doing the locking dance wearing a pair of high stilettos. 

Despite the difficulties, Seulgi perfectly showed off her sharp moves and invited a round of applause. However, she still mentioned prior to the dance that it really is hard to dance in heels. "The day you shoot the MV for girl groups, is the day you die (of pain)," claimed Seulgi.

Moreover, Seulgi talked about the vocal training style of SM Entertainment, how they teach you to hit each note directly instead of bending the vocal line. Check out the videos above and below!
