Actress Park Chae-gyeong, who played "tough girl" Min Sagang in the recently concluded KBS 2TV drama 'I am Sam,' has been cast as the heroine of KBS's "Drama City."

The teen sports drama is about teens who spent their childhood in an orphanage participating in a ball game to win prize money to prevent their orphanage from getting demolished.

'Tae-hee,' whom Park plays, is a big help and mentor to fellow orphanage residents and also develops a romance with one of them.

Park is a fast rising star, winning exclusive commercial deals with Asiana Airlines and Nadry Cosmetics. Her delicate emotional acting in 'I am Sam' has also contributed to her acting career.
