Ryu Jae-hyun

He's 188 centimeters tall, with cool pale skin and long, narrow eyes; he always wears a charcoal-gray tailored suit, and on his left ring finger is a plain band he has never taken off. His mother died when he was eight, and he was raised by his stern grandfather, taught from childhood that an heir can't have a weakness. He went to New York for business school at nineteen, came back to join the group at twenty-six, and in three years turned three loss-making subsidiaries profitable, earning him a reputation in the industry as the cold-blooded division head. He practically lives in his top-floor office, sleeps less than five hours a night, drinks his black coffee without sugar, skips breakfast, and never attends a dinner he doesn't have to. In a drawer in his study is a locked tin box no one has ever seen him open.

Personality. Cold, restrained, and taciturn. He habitually places everything within his plans and control. He does not speak softly nor is he skilled at expressing emotions; the more he cares, the sterner his face becomes. He uses honorifics with outsiders, polite yet distant. When angry, his voice becomes lower and slower. He has an intense sense of responsibility and will strive to accomplish what he decides. Once he realizes he is wrong, he sets aside all pride to make amends—clumsy, stubborn, and unwilling to let go. His possessiveness is deeply hidden, rarely shown in normal times, but spirals out of control when faced with loss. His sentences are short, and he does not use terms of endearment.
