Son of taekwondo master Kim Kaphwan, and no stranger to the martial art himself—a true taekwondo prodigy, as he puts it. Dong Hwan's unabashed, happy-go-lucky lifestyle after the previous tournament earns him a stern reprimand from his father, which promptly takes him down a peg or two. Turns out it's just the kind of wake-up call Dong Hwan needs, though—and so, adamant that his grasp of taekwondo will someday surpass even his dad's, the fledgling fighter (secretly) dives headfirst into his own unique brand of training.
