4. Lee Jung Jae in “Squid Game”

Lee Jung Jae is a legend in Korean entertainment, but it was only this past year that many international viewers got to know this megastar. Having already been known for his ability to meticulously get into character no matter what role he takes on, his role in “Squid Game” as Ki Hoon was no different. Ki Hoon is a character who viewers both dislike and sympathize for, which isn’t an easy feat, but Lee Jung Jae was able to pull this off. He was also recently nominated for a Golden Globe for Best Performance by an Actor in a Television Series – Drama.

5. Koo Kyo Hwan in “D.P.”

There is a reason why Koo Kyo Hwan rose to fame after the success of “D.P.” People couldn’t help but marvel at his dual personality both on-screen and off. In “D.P.,” he plays a charismatic member of the D.P. (stands for Deserter Pursuit) squad. His character is confident and outgoing, but off-screen, he is actually quite shy and introverted. Nonetheless, he became known for his amazing ability to showcase such a lovable character that shows many different sides as he tracks down soldiers who have fled from the army.

6. Kim Seon Ho in “Hometown Cha-Cha-Cha”

Kim Seon Ho took the world by storm in 2020 with his role as Han Ji Pyeong in “Start-Up,” and this past year was really no different. His role as the man of many part-time jobs and skills, Hong Doo Shik, in the healing series “Hometown Cha Cha Cha” won the hearts of viewers from all over the world. The fact that he was acting alongside veteran actress Shin Min Ah and was able to have such sizzling chemistry with her made his role and acting that much more noteworthy. His skilled acting once again proved his wide spectrum that has him shining in any role!

7. Kim Myung Min in “Law School”

“Law School” was a drama of the past year that many fell in love with for its intriguing storyline and mystery. Viewers couldn’t help but wonder what would end up happening at the end of the series. What started off as curiosity in uncovering the mystery became an appreciation for all the incredible acting, especially by legendary actor Kim Myung Min. Known to be rather picky with his K-drama selections, the storyline and his acting chops only proved why “Law School” was worthy of the actor’s choosing. His performance as the cold but very intelligent Yang Jong Hoon was unforgettable.

8. Lee Je Hoon in “Taxi Driver” and “Move To Heaven”

2021 was Lee Je Hoon’s year. Not only did he impress in the action-packed, crime fighting series “Taxi Driver,” but he also moved hearts with his role as former criminal and fighter Cho Sang Gu in “Move to Heaven.” The versatility he showcased through each of these roles was so impressive that it made it almost impossible to choose between the two. His role as Kim Do Gi in “Taxi Driver” was complex as he portrayed several different disguises as a vigilante. It was unforgettable to say the least. And his role as Cho Sang Gu was enough to bring you to tears each episode as he evoked sympathy and healing through his character – Lee Je Hoon is worthy of all the praise!

9. Cha Seung Won in “One Ordinary Day”

Cha Seung Won plays Shin Joong Han in the crime thriller “One Ordinary Day.” He makes quite the impressive duo with Kim Soo Hyun as they both exceeded expectations in their respective roles. Shin Joong Han is a third-rate lawyer who takes Kim Hyun Soo’s (Kim Soo Hyun) case as Kim Hyun Soo becomes a murder suspect. Joong Han is not the most intelligent or well-known lawyer, and many laugh at his abilities, but his willingness and passion to help Hyun Soo drive him to rise to the occasion. This role really marked Cha Seung Won’s further growth as an actor. His ability to portray this aloof, vulnerable character is a side of Cha Seung Won that is more mature and definitely appealing. It makes you look forward to seeing him in his next role!

10. Lee Junho in “The Red Sleeve

How can we forget the man of the season? 2PM’s Lee Junho topped all the brand reputation charts above any other actors this winter. Junho exceeded expectations through his role as crown prince Yi San in “The Red Sleeve.” With the drama being his first series after being discharged from the military, Junho has outdone himself. People couldn’t help but swoon over his romantic lines, sweet gestures, and loving gazes towards his court lady Deok Im (Lee Se Young). And with the series having recently come to an end, fans are still not able to get over the heartache.

11. Uhm Ki Joon in “The Penthouse 2” and “The Penthouse 3

Uhm Ki Joon as Joo Dan Tae is very well one of the freakiest K-drama villains of all time, and we had the pleasure of seeing his evilness for three seasons (two of which aired this past year). Joo Dan Tae emotionally and physically abuses his family, is willing to kill in order to save himself, has no remorse, and would rather see everyone else suffer before his pride is put down. And Uhm Ki Joon was able to perfectly portray all these characteristics. If an actor can make you hate his character this much, then he has succeeded!

12. Lee Seung Gi in “Mouse

“Mouse” is a psychological thriller that viewers were surprisingly blown away by. Not only is the storyline packed with twists and turns, but the two-faced character of Lee Seung Gi’s Jung Ba Reum is also noteworthy. This was Lee Seung Gi’s first role with villainous qualities, and he nailed it, receiving lots of praise from the general public. The duality in which he was able to portray such contrasting characters was incredibly bone-chilling. Hopefully Lee Seung Gi will take on more villainous roles in the future as a result of the positive response!

13. Song Joong Ki in “Vincenzo”

Song Joong Ki plays Vincenzo Cassano, an Italian lawyer and Mafia consigliere who moves back to Korea to solve a conflict he has that involves lots of gold bars. The series was unexpectedly both dark and humorous as viewers saw a violent side to Vincenzo as well as a caring side, especially when it came to Hong Cha Young (Jeon Yeo Been). Song Joong Ki always delivers with his roles, and his portrayal of Vincenzo this past year showed viewers once again why he’s considered to be one of the best actors in the industry.

14. Ji Sung in “The Devil Judge

In “The Devil Judge,” Ji Sung plays Kang Yo Han, a special kind of judge who works in an imaginary dystopian Korea. The biggest mystery in this series is whether or not Kang Yo Han is a hero or a devil, a role in which Ji Sung delivered effortlessly. He is no stranger to playing roles that involve dual personalities, so in this particular drama, he was a natural. The charisma and poise in which he portrayed this particular role made him one of the best this past year, and the drama showcased his veteran acting abilities.

15. Jo Jung Suk in “Hospital Playlist 2”

Jo Jung Suk returned in Season 2 of “Hospital Playlist” as the lovable and outgoing Ik Joon. He is one of five friends who have been close since medical school and all end up working at the same hospital. Ik Joon provides the comic relief among his friends and seems to be much of the glue that keeps the group together. He’s got a big heart and an adorable relationship with his little son. This role almost seemed too natural for Jo Jung Suk, and he always provides such a warmth when he’s on the small screen. Although this was the last of the “Hospital Playlist” series, we can only hope he will return sooner than later in another drama!
