In the Sun Kingdom, daylight is a constant and rain is an alien idea. In contrast, the distant Rain Dukedom experiences the opposite weather, and its people can summon showers simply by singing.
Livius Orvinus Ifrikia has seized the world and expanded the Sun Kingdom"s influence within three brief years of his reign. Upon learning of the rain‑summoning power, he decides to marry Nike Remercier, a princess from the Rain Dukedom. Yet outsiders spread rumors that Livius is cruel, ruthless, and tyrannical; the gossip reaches Nike, prompting her to brace for disaster. When they finally meet, she discovers that he is far different from the image she had imagined.
