K-drama enthusiasts know that the annoying villain or antagonist will surely make everything to destroy the main characters' relationship and life. The characters vary-she can be a rich mother, the resentful second lead, the best friend who hides ill wills, and many more.

While these are kind of stereotypical already, not only in Korea but in other countries, the following characters are the most annoying and hated antagonists in the K-drama realm, according to fans.

1. Kang So Young (Who Are You: School 2015)

Kang So Young (played by Jo So Hyang) raised the tension of the popular K-drama as she played the role of a bully, who continuously oppress and torment Kim So Hyun's character, Lee Eun Bi. Her irritating facial expression shows no remorse, even after the suicide attempt of her victim, annoyed the viewers the most.

2. Yeo Da Kyung (The World of The Married)

Rising actress Han So Hee, who plays the role of a young mistress, is probably one of the most hated characters this year. Her beauty is appealing, indeed. However, viewers can't hide their intense dislike to Yeo Da Kyung after destroying a happy family. Not only this, but the characters around the main character Ji Sun Woo (played by Kim Hee Ae) also betrayed her, raising the tension of the high-rated drama.

3. Queen Jo (Kingdom)

Currently, with two seasons, this drama that can be watched on Netflix is just starting to uncover the origin of the plague. Aside from the magnificent acting of Ju Ji Hoon, who plays the role of crown Prince Lee Chang, viewers can't forget the aggravating role of Kim Hye Jun. To avoid spoilers, we'll refrain from narrating her participation in the thriller drama.

4. Han Je Kook (Graceful Family)

Bae Jong-Ok is a manipulative head in this drama, and viewers can't help but get rid of her character who is blocking Mo Seok Hee to find the justice she wants for her mother. As Lee Jang Woo's role gets involved with Im Soo Hyang, Han Je Kook also became a hindrance not only for him but as well as to his father and uncle.

5. Nam Gyu Man (Remember: War of The Son)

For sure, you have thrown any derogatory and any strong language against this guy. Who wouldn't, though? Played by Nam Goong Min, the viewers witnessed his evil deeds, provoking and making Yoo Seung Ho's role suffer, before facing the consequences he deserves.

6. Jang Geun Won (Itaewon Class)

Starting from a problematic student, Jang caused an accident, taking away the only family of the role of Park Seo Joon. Revenge then became the goal of Saeroy-i as he tried to climb to the social hierarchy. Jang Geun Won, played by Ahn Bo Hyun, was such a capable antagonist.

7. Cho Cheol Gang (Crash Landing on You)

As of now, the role played by Oh Man Seok is probably still irritating for the viewers and fans of "Crash Landing on You." His selfishness, arrogance, and overall personality can really destroy one's day. Luckily, the romance between Ri Jeong Hyuk (Hyun Bin) and Yoon Se Ri (Son Ye Jin) will keep you going.
