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?

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.

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.

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.

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.

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 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.

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.

Si-eun and Young-yi get anxious as they can’t get hold of Soo-ho for too long. After Si-eun finishes his exams, he hears the shocking news. Meanwhile, Bum-seok’s dad tries to make Bum-seok go study abroad.

Si-eun gets beaten up by the guys Bum-seok paid to beat up Soo-ho. Si-eun gets seriously injured, but he doesn’t tell Soo-ho about it to protect Bum-seok. Soo-ho finds out later and decides to confront Bum-seok. Bum-seok pays Woo-young again to beat up Soo-ho.
