Fans can get a glimpse of the actress' refreshing, youthful image. During an interview, Kim So Hyun commented, "I would like to play roles that fit my age and go on to act as different characters from there on."
She added, "Since I'm still under aged, I drank soda during dinner with cast and crew once 'Monarch' was over." Kim So Hyun also looked back on her teenage life as she will be turning 20 years old next year. "I actually experienced an identity crisis at an earlier age than most people. I wasn't forced to think about it. I just wanted to myself."
