Candy Candy is primarily a love story. Candy's first love was a character named Anthony Adley, but the series is remembered by the majority of fans as a result of her heartbreaking separation from her true love and soul mate, Terence "Terry" Grantchester. A recurrent story arc in the series is the "Prince of the Hill", a mysterious boy Candy met as a child and never saw again. His identity is revealed in the last pages of the manga. Once upon a time, there was a little orphan girl crying her heart out on a meadowy hill. It was during this time that she had met her prince—a handsome young boy who approached her, and told her gently to dry her tears and smile instead. The little girl never forgot that memory closest to her heart. Not even after several years later when she travels the path of self-discovery...believing that someday, she will meet her prince again and find true happiness once and for all.
