Netflix just dropped a brand new look into Weak Hero Class 2, and fans are already bracing for another wild ride. The highly-anticipated sequel picks up where the hit first season left off, with Park Ji Hoon reprising his role as Yeon Si Eun—only this time, he’s darker, tougher, and walking straight into a whole new storm.

Now a student at Eunjang High School, Si Eun is still haunted by the trauma of his past. He once tried to live quietly as a “voluntary outsider,” but fate clearly has different plans. The new stills show him locked in a brutal rooftop fight with Geum Seong Je (played by Lee Jun Young), and from the looks of it, the gloves are completely off.

But Si Eun’s not fighting alone this time.

Enter Park Hu Min (Ryeoun), Seo Jun Tae (Choi Min Yeong), and Go Hyun Tak (Lee Min Jae)—new allies who stand by him as the stakes get even higher. The friendship dynamic is a fresh twist, and it’s clear this season isn’t just about solo survival—it’s about brotherhood in the face of chaos.

Of course, no story is complete without villains.

Meet Choi Hyo Man (Yoo Su Bin), the typical bully who crumbles when confronted with real power. Then there’s Na Baek Jin (Bae Na Ra), who’s far more dangerous—a ruthless gang leader with an entire alliance behind him. A still from the teaser shows Hu Min squaring off with Na Baek Jin, hinting at an epic clash between raw street power and calculated brutality.

The teaser doesn’t just promise action—it hints at deeper psychological warfare. With Si Eun’s growing inner darkness and a cast of characters walking the tightrope between loyalty and violence, Weak Hero Class 2 looks ready to deliver more than just punches.

Buckle up. This semester at Eunjang High is going to be anything but quiet.
