After Rin's mother passes away, Rin vows to become a Lady someday and travels to England to join the rest of her family. She is not warmly received, particularly by her stepsister Sara at first, but eventually, they all become a happy family. Rin (Lynn) is also deeply interested in horses and racing, winning a significant number of contests. The series is split into two parts: the first features Rin as a young child, while the second depicts her at around age 13.
