Soredemo Sekai wa Utsukushii

Sun King Livius I has conquered most of the world while still only a boy, yet he has never seen rain. When he learns that the princesses of the Rain Dukedom can summon it through song, he demands one of them as his bride. The choice falls to Nike Remercier, who travels to the Sun Kingdom expecting to meet the ruthless tyrant described by rumor.

Instead, she finds a brilliant and stubborn young king whose loneliness is far greater than his authority suggests. Their marriage begins as a political arrangement filled with clashes, but their differences gradually become a source of strength. Nike's rain-bearing voice opens a part of the world that Livius cannot conquer with an army: another person's heart.
