After gaining critical acclaim on Korean streaming platform Wavve, Weak Hero Class 2 has found global momentum with its recent Netflix release. Premiering on April 25, the second season of the gritty school action drama catapulted the series to international fame, quickly rising to No. 1 in Netflix’s non-English-language content category across 32 countries, particularly resonating in Asia and Latin America.
Based on the hit webtoon, the story follows Yeon Si-eun, a seemingly frail but intellectually formidable student who learns to fight to protect his friends. Park Ji-hoon, known initially as a member of the K-pop group Wanna One, reprises the lead role with renewed depth, proving his transition from idol to serious actor. In interviews, Park expressed a deep emotional connection to Si-eun, describing him as a character that evokes unmatched compassion and melancholy. The final filming scenes left such an impact that he was overwhelmed with tears, as memories from both seasons flooded in and the team’s shared vision came full circle.
In this second season, Si-eun, now burdened with emotional scars, transfers to Eunjang High School. There, he forms new bonds with characters like Park Hu-min, Seo Jun-tae, and Go Hyun-tak, while facing off against the menacing gang “the Union”, led by Na Baek-jin and the enigmatic Geum Seong-jae. Park emphasized that this season was not just about rage-fueled battles. Rather, he aimed to portray a deeper desire to break the endless cycle of violence. As Si-eun evolves, so do the fight scenes, with more sophisticated choreography and creative use of opponents’ belongings.
Park attributes the global success of Weak Hero Class 2 to the timeless appeal of the school drama genre. He believes that the fusion of high-stakes action, bromance, and coming-of-age camaraderie strikes a universal chord. The intense yet relatable friendships among high schoolers and their defiance against adversity resonate with audiences everywhere.
Despite the shift to Netflix, Park said the production approach remained consistent, focused solely on telling Si-eun’s story. Reflecting on his own solitary childhood as a child actor, Park said portraying Si-eun was personally healing. “Watching this boy, who rarely smiled, finally laugh and connect was comforting—it mirrored my own experience,” he shared, solidifying the role as his most personal to date.
