Young Izmir, who married into another country in a political marriage, lost her homeland in a civil war when she was 10 years old. At that time, her much older husband, Graham, guaranteed her safety, quelled the civil war in her homeland, and avenged her parents' deaths. Izmir vowed to repay his kindness throughout her life, but after Graham became king, a certain incident caused him to lose faith in women, and the harem was disbanded. Izmir remained in the harem until she came of age, but eight years have passed since she became a "forgotten queen"—and now, finally, Izmir has a chance to repay her debt.
