Weak Hero Class 1: A Powerful Debut
Overview and Broadcast History
Originally released as an 8-episode Wavve original on November 18, 2022, Weak Hero Class 1 marked a turning point for the platform. It became Wavve's most talked-about title, capturing a 45.5% share of the Korean OTT market. Netflix later acquired the global distribution rights, making the series available in over 190 countries starting March 25, 2025. The show quickly climbed into the Top 10 non-English TV series in 70 countries, remaining there for two consecutive weeks.
Plot and Key Characters
Class 1 follows Yeon Si-eun (Park Ji-hoon), a top 1% student who, despite his frail appearance, uses his intelligence and strategic mind to fight back against the violence at his school. A self-imposed outsider focused solely on academics, Si-eun becomes the target of school bully Yeong-bin. In an attempt to sabotage Si-eun during an exam, Yeong-bin secretly applies a drug patch to his skin. Si-eun's explosive response marks the beginning of his resistance.
As tensions rise, Si-eun is joined by former MMA fighter Ahn Su-ho (Choi Hyun-wook) and Oh Beom-seok (Hong Kyung), the son of a powerful politician. The trio confronts a criminal gang associated with Yeong-bin's cousin, forging a deep friendship in the process. However, Beom-seok ultimately betrays them, leading to Su-ho's serious injury and Beom-seok’s forced departure to the Philippines. Under pressure from Beom-seok’s father, Si-eun is transferred to Eunjang High School, known for its troubled students.
