Get ready to step back into the brutal world of schoolyard survival as Netflix unveils Weak Hero Class 2—the highly anticipated follow-up to the hit Korean drama Weak Hero Class 1. Set to premiere this April 25, the series brings a fresh wave of action, heartache, and emotional grit that fans have been waiting for.

Returning to center stage is Yeon Si-eun, played by Park Ji-hoon, the once-reserved top student who previously took an unexpected stand against rampant school violence. Though Si-eun formed close bonds in the first season, he ultimately loses his friends and is left scarred by the trauma. Now at a new school—Eunjang High—he attempts to start over, only to discover that the battles are far from over.
The teaser trailer sets the tone with Si-eun’s solemn arrival at his new campus. Here, viewers are introduced to a new lineup of characters. Allies include the loyal Park Hu-min (Ryeo Un), the fiery Seo Jun-tae (Choi Min-yeong), and the cool-headed Go Hyun-tak (Lee Min-jae). But new threats quickly emerge in the form of Choi Hyo-man (Yu Su-bin), Na Baek-jin (Bae Na-ra), and Geum Seong-je (Lee Jun-young), promising intense confrontations and emotionally charged rivalries.
Once again, director You Su-min and executive producer Han Jun-hee team up to deliver a raw, gripping portrayal of adolescence, justice, and the strength found in solidarity. The teaser poster—featuring Si-eun’s bruised face, unwavering gaze, and signature stoicism—hints at what’s to come: a vow to protect, no matter the cost.
