[DeepL Translation - needs review] Volume 1 Introduction: Nique, the fourth daughter of the "Principality of Rain," has the ability to make it rain. She reluctantly marries Livius I, the Sun King of the "Sunny Principality," for the sake of her country!　...And she is told that he conquered the world within three years of his accession to the throne, but to her surprise, he is still a child!　And for some silly reason, he demands that she make it rain...!
