KBS weekend drama "My Daughter Seo Young" recently announced the addition of AOA Sulhyun to their cast.

Last weekend, she drew attention to herself, playing a character who seemed to be seducing Sung Jae (Lee Jung Shin). Though it was a short appearance, it had a very big impact.

The only thing that people know is that she is nicknamed 'Seo Young Mini Me' meaning that the two characters are very similar and she appears in similar hairstyles and clothes.

She appears wherever Lee Jung Shin goes and distracts him but leaves no trace of her next steps.

On Sunday, Lee Jung Shin finally goes after her, determined to figure out her true identity.
