Ma Hye Ri passed the bar exam and became a prosecutor with little effort. However, she is simply fulfilling her father's dream and couldn't care less about the cases that come to her. Hye Ri's real interest lies in fashion -- enough so that she skips her initiation ceremony in order to get a rare pair of shoes with the help of lawyer Seo In U, a man who seems to know more than he lets on. Yun Se Jun, the top prosecutor at Hye Ri's office, catches her interest and helps her become a prosecutor who truly cares for her clients.
I Hear Your Voice is about a public defender while Prosecutor Princess is about a prosecutor. In both dramas the female lead gets into her job without having had any interest in it. She isn't liked by her colleagues either. Later on, she grows into her job and gets serious about her cases and finding out the truth behind them.
