Kim Dong Hwan and Kim Jae Hoon are the two sons of Kim Kaphwan, worldwide famous Taekwondo master. A serious practitioner like his father, he enters the King of Fighters tournament to prove himself worthy of continuing his father's legacy.
Jae Hoon is very serious, diligent in his studies, and a charismatic man. He has a strong sense of justice, just like his father. He also has a gentle side to him as he likes the sight of small animals such as rabbits, hamsters, or martens. It's this dedication and compassion which has earned him his own fanclub.
