Do-Hyup Bae

The former boyfriend of Eunhwa. A lazy man who gets tricked into revealing his family secrets to Eunhwa, who then uses them to gain more power. He first fights Gangryong, who he can't defeat on his own, and then he challenges Eunhwa in order to take revenge for her betrayal. He is the successor to his family's traditional martial art, but he is too lazy to master it properly, and he institutes some of Reunion's skills, making it less effective. After his defeat, he gives Gangryong all of his family's secrets and leaves the school.
