Choreographer Lia Kim says she was the harshest on this TWICE member

Choreographer Lia Kim shared about working with top K-pop stars. 

On the December 11 airing of MBC Every1's 'Video Star,' Lia Kim revealed, "I was in charge of the choreography for Girls' Generation, Lee Hyori, 2NE1, EXID, Sunmi, Uhm Jung Hwa, TWICE, and more," and named TWICE and Sunmi as her students she treasures the most. 

The MCs asked, "You  favor JYP artists?" Lia Kim answered, "I provided training there for the longest so I grew fonder. I've scolded them a lot and even made some of them cry." 

G-Friend's Yerin, who joined as the special MC of the day, commented, "The scariest person during the trainee days is the choreographer." 

Lia Kim continued, "I yelled at them to do it right when they get it wrong. I'm apologetic to Jungyeon because I was especially harsh on her."
