Although SNSD's Sooyoung is a name well-recognized across South Korea, her older sister has yet to become a familiar face. But that may soon change, however, thanks to the lead female role Choi Soo Jin nabbed for the stage version of the famous TV drama, 'Winter Sonata'. Choi Soo Jin, who will play the role of 'Yoo Jin', has also participated in musicals in the past, including 'The Wizard of Oz', in addition to singing for soundtracks of popular dramas like 'The Greatest Love'. 'Winter Sonata', which will begin playing on September 27th at the Myungbo Art Hall, will also star Kim Tae Han in the dual roles of 'Jun Sang' and 'Min Hyung', which were filled by Hallyu star Bae Yong Joon in its initial 2000 broadcast.
