Wave has released the teaser trailer for its highly anticipated first original drama of 2025, ONE: High School Heroes. Based on the hit webtoon ONE, which racked up over 65 million views, the drama tells the story of top student Ui-gyeom (Lee Jung-ha) and street-smart Yoon-gi (Kim Do-wan) as they form a masked duo to fight school violence and challenge the existing hierarchy.
The teaser shows Ui-gyeom discovering his hidden fighting talent after transferring schools, while Yoon-gi sees potential in him. The pair take down bullies one by one, with a chilling scene of Ui-gyeom standing in a bloodied hallway declaring, “The problem is that there are too many bad guys in the world.”
Also joining the cast is Yook Jun-seo as the mysterious fighter Geol-jae. The action-packed trailer promises stylish visuals and powerful chemistry between the masked hero duo.
ONE: High School Heroes premieres exclusively on Wave this May.
