According to the Korean media outlet The Star, Jin Se Yeon has taken the role of prison advocate Ok Nyeo in the 50-episode Joseon-era drama "The Flower In Prison," also known as "Ok Joong Hwa."

Ok Nyeo is a woman who was born in prison and spends her life helping the imprisoned. During the Joseon era the Korean legal system was less formal and so mediators such as Ok Nyeo helped mediate on behalf of those charged with crimes. She uses a private litigation system known as Wae Ji Bu.

Jin's character is not a real person but the historical drama will feature some real-life events and actual historical figures.

Jin Se Yeon has only been acting for a few years but she's managed to land some impressive roles. She made her debut in 2010 with a supporting role in "It's Okay Daddy's Girl." After that she played Joo Won's doomed bride in the 2012 historical drama "Bridal Mask." She had a leading role in the 2014 dramas "Inspiring Generation" with co-star Kim Soo Hyun and she also played Lee Jong Suk's spy agent love interest in "Doctor Stranger." None of these characters were easy to play. She's only 21.

"I think I still have a lot of growing up to do, but I've had to play mature characters who must endure many trials and tribulations, including extreme solitude," Jin said in an interview with the media outlet Chosun Ilbo.

In 2015 she took a break from serious roles to play a detective in the narcotics squad in the comedy film 'Enemies In-Law," which was a spin-off of the film "Meet The In-Laws." She's a cop from a family of cops and he's a criminal from a family of criminals. But he will move to the right side of the law for her.

Jin's most likely co-star in "Flower in Prison" is actor Go Soo. Last seen in the drama "Empire of Gold" and the film "The Royal Tailor," Go Soo is currently considering a role in the film. Park Joo Mi, who appeared in the drama "Blood" will play the character Jung Nan Jung.

Lee Byung Hoon, who directed the historical hit dramas "Dong Yi" and "Dae Jang Geum," will direct "The Flower in Prison." Choi Wan Kyu, who wrote the screenplays for "Triangle," "All In," "Iris" and Guam Heo Jun" will write the script.

Jin Se Yeon begins filming her new drama in mid to late February. "The Flower In Prison" is expected to premiere in March, following the end of "My Daughter Geum Sa Wol."
