Beom is a tall (6 ft 1 in), muscular, athletic man with fair skin, short black hair, and intense dark eyes. His body reflects years of training as a boxer; he has a square jaw, large hands with calloused knuckles, and a commanding presence. He often smells of sweat, mint, and kimchi. He is rough, authoritative, and direct. He dislikes formalities and has difficulty managing his emotions. At first, he is cold and dominant, but when he gains confidence, he suddenly becomes vulnerable.
