Weak Hero: Class 1 - Episode Guide

Jeon Yeong-bin picks a fight with Yeon Si-eun only to be stopped by Ahn Su-ho. Then, he decides to use Oh Beom-seok to attack Si-eun.

Si-eun doesn't back down and reveals the truth about Yeong-bin, but Yeong-bin seeks revenge.

Kim Gil-su learns that Jeon Seok-dae and his gang were thrashed by a nerdy-looking kid, and gets furious.

Si-eun discovers Su-ho's blood on the floor and that the house has been emptied out. He calls Yeong-i for help.

Beom-seok runs into bullies from his old school, and Su-ho makes them apologize to Beom-seok.

Su-ho and Beom-seok's friendship shatters. Si-eun tries to help, but Beom-seok's growing insecurity leads to a dark plan.

Beom-seok's plan unintentionally puts Si-eun in trouble. Si-eun chooses silence over conflict, but Su-ho senses something is wrong.

Having crossed a point of no return, Beom-seok regrets his actions but it's too late. When Si-eun discovers the truth, he takes decisive action.

Still affected by what happened to Su-ho, Si-eun withdraws from others. Seo Jun-tae contemplates taking a stand against the bullies — despite the risks.

After being saved by Si-eun, Jun-tae attempts to befriend him — but both are soon dragged into Choi Hyo-man's revenge plot involving Go Hyun-tak.

While doing volunteer work as punishment for fighting, Si-eun begins to form a bond with new friends — but trouble continues to find him.

After Geum Seong-je crosses the line, Si-eun strikes a deal with Na Baek-jin — leaving Park Hu-min, Hyun-tak and Jun-tae alone in the violent crosshairs.

Worried for his father and backed into a corner, Hu-min confronts Baek-jin. Si-eun considers studying abroad after clashing with his distressed mother.

Si-eun, Jun-tae, and Hyun-tak seek out Hu-min, who has decided to work with Baek-jin to keep the peace. Still, Hu-min finds it difficult to comply.

As Si-eun's absence leaves a gap, Baek-jin presses on with his violent mission. In response, Hu-min rallies his school and challenges him to a showdown.

Hu-min, Hyun-tak and Eunjang students gather to engage in a final confrontation against Baek-jin's gang. In the end, who will prevail?
