In SBS's upcoming drama, 'Heirs,' Krystal turns into 'It Girl' Lee Bo Na, who is an heiress to a large entertainment empire.

Krystal had her first shoot last month on the 17th.  With a refreshing and lively attitude, she greeted the other actors and talked freely.  However, as soon as the cameras started rolling, she became chic and elegant Lee Bo Na dressed in a knit skirt and walking with purpose (watch out, civilians!).

Despite her busy schedule, Krystal has been working diligently to learn the script and portray Lee Bo Na.  She said, "I tried my best to immerse myself in the character.  I will work harder until I am able to think and speak like Lee Bo Na."

Krystal sure has the look down as well as the determination, but fans will have to wait until the October 9th premiere to really decide how well she plays the part!
