Park Ji Hoon and team fist up against the Union in 'Weak Hero Class 2'

Netflix series Weak Hero Class 2 has unveiled intense teasers.

Weak Hero Class 2 is a tale of growth and survival of model student Yeon Si Eun (Park Ji Hoon), who transfers to a new school carrying the trauma of failing to protect a friend while standing against violence. Determined never to lose another friend again, he confronts greater violence, unfolding a desperate struggle for survival.

The main posters feature Yeon Si Eun (Park Ji Hoon) gazing somewhere with a scarred face, hinting at the storm that's about to hit Eunjung High. Similarly, the determined Park Hoo Min (Ryeo Un), Seo Jun Tae (Choi Min Yeong), and Go Hyun Tak (Lee Min Jae) stand alongside Yeon Si Eun to "Fight to End it."

The trailer begins with Yeon Si Eun walking calmly through a crowd of delinquent students, followed by the introduction of Union, a group of all school gangs in the area. Yeon Si Eun's chilling warning to Na Baek Jin, who sits at the top in Union, raises questions about the incident and reasons that led them into conflict.

Meanwhile, the trailer introduces Park Hoo Min. Known as "Baku," a powerful and well-known figure in the area, he is not only physically strong but also brimming with justice — and stands as a protector of Eunjung High against the Union's grasp. His gentle gesture of reaching out to Yeon Si Eun, saying "You don't need to worry about stuff like the Union anymore," contrasts sharply with his fierce expression as he raises his fist toward Na Baek Jin. Na Baek Jin's words, "I still think of you as a friend," further deepen the intrigue around their fraught relationship.

With Park Hoo Min declaring, "Let's end this," the trailer ramps up with even more intense action. As Yeon Si Eun, Park Hoo Min, Seo Jun Tae, and Go Hyun Tak confront violence both inside and outside of school to protect what matters most, all eyes are on how their battle with the powerful Union — including Choi Hyo Man (Yoo Soo Bin), Na Baek Jin (Bae Na Ra), and Kim Geum Seong Je (Lee Jun Young) —will unfold. 

Weak Hero Class 2 is coming April 25, only on Netflix. Watch the trailer here.
