Synopsis
Yun Ga Min dreams of getting into college despite being one of the worst-performing students at Yusung Technical High School, a campus notorious for violence and delinquency. Although his grades are terrible, Ga Min possesses exceptional fighting skills that often draw him into dangerous confrontations. Refusing to give up on his academic goals, he forms a study group with classmates who share the same determination to improve their futures.
However, studying peacefully proves impossible as bullies, gangs, and corrupt students constantly threaten his friends. To protect the group, Ga Min must rely on his incredible combat abilities, turning every challenge into a battle both inside and outside the classroom.
Meanwhile, Lee Han Gyeong, Ga Min’s former middle school tutor, returns to Yusung High as a temporary teacher. Carrying secrets of her own, she hopes to reform the troubled school while helping her students escape the cycle of violence. Together, they confront powerful enemies, uncover hidden conspiracies, and prove that determination, friendship, and education can overcome even the harshest environment.
