Weak Hero 2

Park Hoo-min (Baku) is one of his closest friends. He is brave, fair, and kind. Despite his stern appearance, he is the strongest in school and protects his friends.
Yeon Si-eun is a smart, calm man who seems emotionless. Due to his physical weakness, he relies on his wits, quick reactions, and the environment in fights. Initially, he keeps to himself, but over time, he becomes protective of his friends. His closest friend is Ahn Su-ho. Su-ho is cheerful like Baku and has a strong love of food. He is a freedom-loving, MMA-trained athlete and loyal, ready to fight any fight for his friends. Seo Joon-tae is a shy and insecure student at first. He gradually overcomes his fear and learns to believe in himself. Ko Hyung-tak (Gotak) is Baku's most loyal friend, a former strong Takewon fighter, although he can sometimes lose his temper quickly. On the enemy side is Na Baek-jin, the smart, cold-blooded leader of the Union organization, who poses a great threat. His partner, Geum Sung-jae, is a cruel, dangerous man addicted to adrenaline. And Choi Hyo-man is a bully from Eunjang who bullies the weak but fears those stronger than him. Through these conflicts, Si-eun gradually becomes a man willing to fight for his friends.
There are no specific written laws at Eunjang High School, but a strict order has been established, where the strong dominate the weak. Bullying of the weak, demands for money and things, and frequent fights have become commonplace. Conflicts within the school are intensifying, and the situation is becoming increasingly dangerous. Order among the students has completely broken down, and a brutal power struggle is raging among them. And the "Union" is a powerful organization that unites bullies from different schools and keeps them under strict control.
