Netflix released the official poster and trailer Tuesday for its upcoming series "Weak Hero Class 2," the sequel to the 2022 hit "Weak Hero Class 1."
The new season follows Yeon Si-eun, a model student who transfers to Eunjang High School burdened by trauma after failing to protect a friend from violence. Determined never to lose another friend, he finds himself once again standing against even greater violence.
Portrayed by Park Ji-hoon, Yeon faces off against a mysterious new rival, Geum Seong-jae, played by Lee Jun-young. In the trailer, Yeon's says remorsefully, “Suho, I got into another fight. I’m sorry,” hinting at the unresolved scars from his past.
Having lost his smile and become a self-imposed outsider, Yeon struggles to stay unnoticed, but disturbing rumors soon target him again.
New characters Park Hu-min (Ryeoun), Seo Jun-tae (Choi Min-young), and Ko Hyun-tak (Lee Min-jae) approach him with kindness, telling him to ignore the gossip. Though he initially shuts others out, Yeon slowly lowers his guard and accept their friendship.
“I forgot how good it feels to have friends,” Yeon says tearfully in one scene.
But even at Eunjang High, the violence doesn’t stop. New threats inside and outside the school push Yeon to the edge, further fueling his rage.

Adding to the anticipation, the newly released poster and teaser offer a glimpse of what lies ahead. Though battered and bruised, Si-eun’s unyielding gaze signals that his fight is far from over.
The tagline, “Stand To Protect It,” heightens curiosity about the greater violence awaiting him at his new school, as he continues to carry the weight of past trauma.
The first season of "Weak Hero" was widely praised for its emotional depth, portraying Si-eun’s painful but powerful journey as he broke out of his shell, formed bonds with his friends and found the courage to stand against a harsh reality.
Originally produced as a Wavve original series, Season 1’s critical success helped fuel anticipation for Season 2, which is now being produced as a Netflix original, drawing further attention.
