In an imaginary world where Korea is one of the world's leading nations in martial arts, its government encourages high schools to set up martial art classes to develop talented martial artists. As the government provides numerous benefits to the students of these classes, almost all teenagers dream of being selected for the special classes. Among the martial arts classes all over the country, Namil High School's Martial Arts Class 3 is the most famous. Jitae's training doesn't appear to be as fruitful as his teammates and coaches would like, but once he gets in the ring, it is clear to other fighters that there is something special about him. His struggles don't end there, as he becomes more intimidated by his new classmates, who all seem bigger, stronger, and more together than himself. But that may not actually be the case, which Jitae learns as part of Maria's past becomes more clear. A bit of jealousy from another student about Jitae and Maria's relationship puts the young man in danger...but he's not the only one. Jitae's friends and former classmates, Ok-Dong and Jieun, find themselves in a bit of trouble with the school bullies that continues to escalate, no matter how hard they try to fix it. Will this put Jitae and the bullies on a collision course that will make the new fighter finally have to learn how to use his abilities?
