Minjung's attempts to copy Wondergirl Sohee's facial expression has become an issue. 

On "One Night's TV Celebrity" program, many celebrities including Youknow Yoonho, Sohee, and Yoon Dohyun were interviewed. 

Lee Minjung, who was also interviewed, said "I'm so excited to meet all of you for the first time. Especially, Sohee - I always want to see her cute expression" and tried to mimic Sohee.

Later, she even went so far as to ask Sohee to show her signature smile and Sohee, though startled at first, complied.

Viewers have commented, "They're both so adorable!" "Sohee's chic expression is attractive"
