What happens in Weak Hero Class 2?

When we left Yeon Si-eun (Park), he’d just transferred to Eunjang High from his former school, Byuksan. He was expelled from Byuksan after his best friend Oh Beom-seok (Hong Kyung) betrayed him, while his other best friend, Su-ho (Choi Hyun-wook), was left in a coma after a violent altercation with bully Jeon Yeong-bin (Kim Su-gyeom) and his cronies. Now, along with his new classmates Park Hu-min (Ryeo), Seo Jun-tae (Choi), and Go Hyun-tak (Lee Min-jae), a traumatized Si-eun must gain the strength to face up against Eunjang’s most notorious tough guy, Choi Hyo-man (Yu), and his gang of thugs. Hyo-man, who squared off with Si-eun at the end of Weak Hero Class 1, is determined not to let Si-eun get in his way — or jeopardize his path into the Union, a network of high school gangs run by an unassuming student.
