More about Lee Jung-ha and Kim Do-wan’s characters in ONE: High School Heroes
One: High School Heroes is based on a webtoon of the same name, written by author Lee Eun-jae. The webtoon received 65 million views on Kakao Webtoon. The webtoon won the 2020 Today's Cartoon Award. Due to this, anticipation for the drama helmed by director Lee Sung-tae was at an all-time high.
About Lee Jung-ha’s role in the series, director Lee Sung-tae shared his thoughts in the press conference on May 28, 2025.
“Lee Jung-ha is a bright and cheerful actor who resembles the repressed character of Eui-gyeom remarkably. I was impressed by the moments when he naturally created emotions and his eyes turned scary," he said (as translated by Google Translate).
In ONE: High School Heroes, Kim Eui-gyeom depicted by Lee Jung-ha, is a bright student who stays away from the troubles happening in high school and only focuses on his grades. He has nightmares after losing his brother, Kim Soo-gyeom, who committed s*icide. Notably, Kim Eui-gyeom's father, Kim Seok-tae, coerced him to always come first and burdened his son with high expectations.
Additionally, the director also shared his thoughts on actor Kim Do-wan's skills and his character.
"I really wanted to work with him after seeing his previous works. He's a good person and a good actor. But most of all, isn't he handsome? That was the best part,” he said (as translated by Google Translate).
Kim Do-wan portrays the character of Kang Yun-ki, Kim Eui-gyeom's classmate at his new school. When Kim Eui-gyeom got into fights with the bullies, Kang Yun-ki examined his moves.
Kang Yun-ki is great at analysis and is a trained fighter himself. This helps him provide instructions to Kim Eui-gyeom in fights so that he can easily take down the bullies.
Meanwhile, viewers may catch up with ONE: High School Heroes on Wavve.
