Parasite OF COURSE

One

South Korean

This guy played the young TaGon in Arthdal Chronicles Part 1: The Children of Prophecy and I thought the character really suits him not only because of his good looks but also because he gives off a certain aura where it's hard not to notice him. I was surprised when I found out that he was also a rapper and even more surprised when I actually already saw him before and that was in one of his own music video called: «해야해(heyahe). No wonder I liked him immediately. 

Yoo Teo

South Korean

Even though Soong Jong Ki was the main reason I watched Arthdal Chronicles Part 1: The Children of Prophecy I found myself distracted by a new face. Yoo Teo played the character of Joong Ki's father in the serie. He didn't have a lot of lines but every time he would appear on screen and especially that one time (sorry I can't spoil it) his presence is never unnoticeable. I know he has upcoming projects and I can't wait to see him again on the screen! Just from that one scene, I instantly knew he had great potential. 

Tan Jian Ci

He played the role of Cao Pi in Secrets of Three Kingdoms.  It's incredible to see how his character has developed from the first episode and you clearly see how and why he had to take a different path. 

Hong Yao

That's my chinese Hyun Bin. The man has been acting on to many supporting roles GIVE HIM A MAIN ROLE MAN.

Lee Joo Young

South Korean

So I've seen people mentionning her in other dramas like Weightlifting Fairy Kim Bok Joo, Something in the Rain but I never even realized she was in there. However, her role in the drama Itaewon is very intriguing, I'm currently at episode 5 and her character is seriously starting to pique my interest

Nam Da Reum

South Korean

Don't get fool by this young actor, he does a good younger version of every male lead actors in every dramas I've seen him in. 

Lee Soo Hyuk

South Korean

Ok, Mr. Lee. I see you. You've proven yourself in Born Again. You ain't just a pretty face I have to admit, but I want to see more!

Kim Kyung Nam

South Korean

I saw him for the first time in Come and Hug Me. He was portraying Yoon Hyun Moo, the brother of the main protagonist Yoon Na Moo.  Yoon Hyun Moo was the older son and he wasn't really nice with his younger brother Yoon Na Moo. He would always get in trouble at school and his father was more proud of his younger brother because he excelled in everything.  His role was very detestable at first but his character develops in the story.  We can't help but slowly feel compassion towards the poor Yoon Hyun Moo and that wouldn't be possible without the excellent performance of Kim Kyung Nam.

Park Ju Hyun

South Korean

Currently watching Extracurricular with her as ''Bae Gyu Ri''. I'm putting her on this list but I know she'll be well known later on.  Her capability in switching emotions is incredible. 

Jang Dong Yoon

South Korean

Kang Tae Oh

South Korean

He made such a badass entrance in the drama the tale of Nokdu.

Yim Si Wan

South Korean

All I can say is , watch  Strangers from Hell 

Lee Hyun Wook

South Korean

Watching him play a psycho/serial killer twice in Strangers from Hell and The Good Detective has convinced me of his capability as playing the role of a villain. His smile gives me chills. O_O

Jeon Jong Seo

South Korean

Amazing performance as a psycho serial killer in The Call
