Actress Moon Geun Young is currently starring in the new KBS drama Cinderella's Sister. She's portraying a rather wicked personality through the drama as compared to her past roles. But this isn't the only change as "the nation's little sister" wants to grow up. On the April 8th episode of Happy Together, MC Park Myung Soo asked how Moon Geun Young felt about being dubbed as the "nation's little sister". She replied that although she likes it, the title is now best suited for Olympic skater Kim Yuna. Given Moon Geun Young's age (23), she figures it's time to grow up and pass down the title of "little sister" and thinks "the nation's actress" is a more honorable title. When asked if she could be called anything, she replied that she wished people would call her the "very sexy Moon Geun Young". Seems like only yesterday that Moon Geun Young was 17 and capturing the hearts of many with her adorable performance in My Little Bride. Now that she's aged, she wants to be seen as a more mature and sexy actress. What do you guys think, can she do it?
