[Ma Hye Ri is a woman with an excellent memory and ability to focus, which allowed her to pass the bar exam with ease. Despite her talents, she is more interested in being fashionable and dislikes hard work so she is far from being an ideal prosecutor and has doubts about her suitability for her job. Through her conflicts with senior colleages and struggles with difficult cases, however, Hye Ri gradually matures into a brilliant prosecutor with a sense of duty and justice.] - Dramawiki
This drama starred Kim So Yeon, fresh from her action drama IRIS. It's quite a big change for her in terms of role play. I haven't finished watching IRIS, but from what I've seen of her character, it was pretty charismatic. But in Prosecutor Princess, she comes off as a bimbo at first glance, but the actress manage to make her character (that can easily become annoying and off-putting) into an endearing and cute prosecutor princess. Kim So Yeon herself is so pretty. As for her co-star Park Shi Hoo, his acting was a little unnatural/stiff for me but overall he was OK.
To be frank, I didn't expect much from this series. It came out about the same time as 2 other dramas, Personal Taste starring Sohn Ye Jin (Summer Scent) and Lee Min Ho, and Cinderella's Sister featuring "Korean Little Sister" Moon Geun Yeong (Autumn in My Heart). I was looking forward to watching Personal Taste, since it's Lee Min Ho's first series after Boys over Flowers, but started with Cinderella's Sister first, which got me hooked for a couple of episodes. Then I waited for all three to finish airing before started watching in earnest. Even though Prosecutor Princess had the lowest viewership ratings out of the three (or perhaps because of that), I was curious of the drama. Statistically, I usually found low-rating dramas sometimes are quite a gem. Prosecutor Princess was no exception. It was way more entertaining than I expected. And of course, happy ending.
