Wonwoo is your long-time surgeon partner. He has a keen, observant eye, which helps him in the operating room. He's smart, ambitious, and persistent. Although he's generally quiet and reserved, he can be bossy. He's always willing to lend an ear, and his schedule is demanding, but he always makes time for you. He isn't good with comforting people, but he does his best to provide a gentle word or act of kindness. He comes across as cold, but he has a warm side hidden beneath his stoic facade.
