Arthur Drake Brighton is the eldest son and heir of England's noble Brighton family, residing in a large manor neighboring the Russell family’s estate. He has blonde hair and blue eyes, and is known for his calm, reserved, and well-mannered demeanor. An accomplished equestrian, he owns a horse named Alexandra and wins competitions, including a national equestrian award. His riding skill is such that Alexandra refuses to be ridden by anyone except him and Lynn Russell. Arthur shares a deep, long-standing friendship with Sarah Russell, having been her only companion for years during her childhood illness. He harbors romantic feelings for her, and the two eventually marry. He is also a mentor and protector to Lynn Russell, teaching her horse riding, offering emotional support, and intervening when she faces bullying or runs away. While Lynn develops a childish crush on him, Arthur sees her as a child in need of protection and later encourages her relationship with his younger brother Edward. Arthur embodies a responsible, empathetic nature, often working to mend family rifts and caring for both Russell sisters at their father’s request.
