About

A gritty action-growth drama following Yeon Si-eun, a top 1% model student who looks fragile but uses his natural intelligence and analytical skills to fight against violence inside and outside of school. Yeon Si-eun, Oh Beom-seok, and Ahn Su-ho were close friends, but the relationship shattered when Beom-seok, consumed by inferiority, began hanging out with a group of delinquents. Beom-seok held a grudge against Su-ho and recruited Kang Woo-young with money, even causing Su-ho's leg injury by tampering with his motorcycle brakes. When Beom-seok's gang took Young-yi hostage to lure Su-ho out, Si-eun went in his place and was badly beaten. Learning this, a furious Su-ho headed to the gym. He defeated Kang Woo-young in the ring, but was ultimately left in a vegetative state after being jumped by the gang outside. Following his friend's tragedy, Si-eun retaliated against everyone involved and was forcibly transferred to Eunjang High. Si-eun intended to graduate quietly without getting involved in danger, but Eunjang High, where violence is a daily occurrence, would not leave him alone. In the process, Si-eun met new friends like Seo Jun-tae, who approached him with sincerity, and the loyal Park Hu-min and Go Hyeon-tak. Seeing his precious friends suffer from unjust violence again, Si-eun gave up his plans to study abroad. He decided to break down his walls and stand together with his friends to fight back. The enemy this time is the massive 'Shuttle Patch Alliance' that has grown in power by crushing surrounding schools. As threatening figures like Geum Seong-je and the Alliance head Na Baek-jin—who possesses both a meticulous brain and overwhelming fighting skills—pressured Eunjang High, Si-eun and his friends began to face the giant force head-on to protect their daily lives and each other. Yeon Si-eun continued to shake up the board in his own way using superior intelligence and tools, shaking off past guilt with the determination that he "will never lose a friend again." It is a desperate and brilliant struggle, showing him enduring through even more brutal violence, healing his wounds, and achieving true solidarity and growth. Eventually, the Alliance and Eunjang High clashed, ending in Eunjang's victory and the return of peaceful days. The story concluded with Ahn Su-ho waking up from his coma and meeting Yeon Si-eun while in a wheelchair.
