During a time when the more experienced actors in their 30s and 40s are hitting their peak, the actors in their 20s are also showing their prowess.

These three actors have successfully captured the hearts of audience members everywhere and have been very key in drawing ratings for their dramas. Starting with Jang Keun Suk, Kim Soo Hyun, Yoo Ah In, Lee Seung Gi, Park Yoo Chun and Joo Won, the actors in their 20s are poised to take the stage.

◆ Song Joong Ki, Extends His Acting Range

It wouldn't be an understatement to say that the hottest actor is Song Joong Ki (28). He is currently starring in KBS's drama "Nice Guy," playing the role of Kang Ma Ru, who has been betrayed by love and now is the typical bad boy.

Last year, he received amazing reviews in the SBS drama, "The Tree with Deep Roots" and this drama was his comeback after a year hiatus. He defeated all the worries that people had about whether he would be able to play a heavy role like this and is now known as an actor's actor.

His challenge didn't stop here. His movie, "Wolf Boy" recently premiered and he also turned people up on their heads with their assumptions that he would play just another pretty boy. 

Many who have closely watched his acting say that his dynamic expressions and charming low voice is key to his appeal. He has a very big range, from comedic performances to these serious types of roles and even playing a wolf. He is constantly challenging himself and people are wondering what his 30s will bring. 

◆ Park Yoo Chun, No Longer An Idol

Park Yoo Chun, who first garnered attention with SBS's "Rooftop Prince," will star in MBC's drama "I Miss You" which is set to air in November. 

"I Miss You" is a love story between a man and a woman who have both been hurt by their first loves that left them heartbroken at 15 and Park Yoo Chun plays Han Jung Woo, who becomes a detective who is still unable to forget the woman who stole his heart. His first love will be played by Yoon Eun Hye. 

Park Yoo Chun started his acting career with KBS "Sungkyunkwan Scandal," and was awarded the New Face award. He continued onto MBC "Miss Ripley" and SBS "Rooftop Prince," solidifying himself as an actor in the industry. 

He was able to pull of a comedic performance in "Rooftop Prince" and the way that he portrayed his feelings towards his counterpart Park Ji Min was incredibly real and very romantic. 

Park Yoo Chun also dispelled any doubts about him as an actor and people are anticipating just how much of a change he will undergo yet again in his new drama.

◆ Joo Won, Fast Growth As An Actor

Joo Won has proven himself to be lucky when it comes to ratings. 

After many successful dramas including KBS "Baking King Kim Tak Goo," "Brothers of Ohjak Bridge," and now "Bridal Mask," he has transformed himself into a very legitimate actor. 

"Bridal Mask" was a very good match for him. He had to portray Lee Gang To and Bridal Mask in the movie and had to show two extremes of emotions in those two different characters. He warranted very positive reviews for his performance and shocked people with every episode.

He has been cast in MBC 'Secret Male Female Story' that will air in January of 2013. The drama will portray young intelligence officers who experience love, friendship and conflicts within their working environment. 

Joo Won will play an agent who has always dreamed of being a secret agent and had had a very smooth life thanks to his wealthy father. He's relatively positive about life and nice to people but faces many challenges once he gets into the organization of his dreams. 

After "Bridal Mask," Joo Won said, "I want to try roles that are appropriate for my age. I think romance is definitely the hardest thing ever but I have to try it now while I still can. Whether I can do a good job or not, I still want to try it." Whether he will be able to bring his increased acting ability to the screen in the romance is still a mystery but viewers will be excited to see him when he comes back.
