Two idols,�SECRET's Sunhwa and�Dal Shabet's�Ahyoung, have been cast in an upcoming KBS drama 'Advertisement Genius Lee Tae Baek'.

Sunhwa will play the role of Lee Tae Baek's younger sister, Lee So Ran, who is a narrator model who dreams of becoming an actress.

Sunhwa shared, "Although I am nervous and excited because it is my first time acting, I will do my best to learn, feel, and work hard on set. The character of 'Lee So Ran' is very similar to my real personality, so I already feel close [to the character] and am excited. I work hard so that I will be able to receive compliments that Sunhwa has potential in acting."

Meanwhile, Ahyoung will play the part of�Gon Sung Hye, a junior that is majoring in design. She plays the secretary of the owner of an advertisement company,�GRC.

Ahyoung's character is a slightly 4D girl who always uses internet phrases such as 'hul', and has her own unique sense of fashion and hairstyle.

Ahyoung said, "It's my first time acting in a real drama, so I'm worried. But I'm working hard to learn with my sunbaenim's help. I'm looking forward to showing off new sides of me that I haven't been able to show my fans. Please show me a lot of support."

'Advertisement Genius Lee Tae Baek' will air after 'School 2013'.
