ONE: High School Heroes, starring Lee Jung-ha, Kim Do-wan, Yuk Jun-seo, and more, completed airing all the episodes on Wavve on June 13, 2025. The series follows the story of two red-masked students who start a mission to take down bullies.
At the end of ONE: High School Heroes season 1, Kim Eui-gyeom wins the fight against Choi Ki-soo (Yoo Hee-jae). Choi Ki-soo is severely injured; however, what happens next is unclear. This is because Choi Ki-soo previously hints at Kim Nam-hyub’s father's involvement in Jin-soo’s tragic incident. What role Kim Nam-hyub’s father plays in covering up this incident is a mystery.
Kim Eui-gyeom (Lee Jung-ha) and Kang Yun-ki (Kim Do-wan) are also transferred to a mysterious school, which could serve as the foundation of a potential chapter. Moreover, Yuk Jun-seo’s character, Lee Geol-jae, and Lim Sung-kyun's character, Kim Seung-joon, are intriguing but aren't seen enough.
