AOA member Seolhyun finally made her first official appearance on KBS weekend drama "My Daughter Seo Young" on the Sunday episode. 

She plays Seo Eun Soo, an acting teacher at a management company and appears in front of Sung Jae (Lee Jung Shin). She appears almost very similarly to his sister-in-law Seo Young (Lee Bo Young) and finally reveals her identity. 

On the Sunday episode, Sung Jae was auditioning for an acting part and is shocked by the mini Seo Young. Though he messes up the audition because he was distracted, he is still approached by the management for his good looks.

He signs with the management company and begins training as an actor. The lesson was being taught by the teacher, who kept appearing and disappearing in front of him, Seo Eun Soo.

He is shocked by the similarities between Seo Eun Soo and Seo Young, when he first met her as his tutor. 

Internet users said, "Sulhyun is so charismatic!" "She's so good at acting! Can't be a newbie!" "Wonder what will happen between them!"
