About ONE: High School Heroes

Nam Seung-Sik used to be the star student, a kid others looked up to until a cruel home life and relentless bullying reshaped his days at school. After surviving those pressures, he finds a new path alongside a group of teens who refuse to stay silent. The crew pulls together to shield classmates from bullies and to push back against a pervasive culture of fear. As relationships tighten and loyalties form, the group's actions spark a larger conversation about power, resilience, and the price of change. Their first operation threatens more than bruised egos, forcing them to confront the consequences of standing up. The series uses tight pacing and cameras to keep stakes high, weaving in moments of doubt amid action.

Directed by Lee Seong-tae, 2025 series ONE: High School Heroes presents an original idea brought to life by an ensemble. Shin Jun-seop, Shin Jae-whi, Lee Jung-ha, Kim Do-wan and Kim Sang-ho lead cast and give the show a social edge.

As of now there are no major awards announced for the show and no wins listed. Critics have not highlighted it in top ceremony categories yet, though the central performances by Shin Jun-seop and the supporting cast have drawn positive chatter online. Its ensemble and craft could attract future nominations.

Even at this early stage the show is sparking conversations around school violence and resilience. Fans are debating the portrayal of abuse and the group's duty to protect peers, while the cast's chemistry fuels social media buzz and hopeful comparisons to real life actions. Its impact grows as audiences connect.

Critics note a brisk, action oriented style paired with character driven drama. Central themes include overcoming oppression, reclaiming power, and choosing solidarity over fear. The show threads tense confrontations with moments of quiet vulnerability, offering a clear-eyed look at modern adolescence. The show invites debate about power and community today.
