What I felt about Song Hyekyo is that she is a courteous and calm person. She is not talkative and she treats people in a very polite way. However, according to the people who are very close to her, she is very cheerful and easily makes friends, which means she is shy of strangers but she behaves in a family way when she’s with her best friends. That’s why some of people in the Korean entertainment world say she acts like a princess, while her close friends say she seems like a guy in a woman's body.
