Synopsis: Akuratsu Koutei to Chouai Kazoku Keikaku

Natalia Soares lived a quiet life, peacefully growing crops in the lush territory of Flourish. But one day, she is suddenly chosen as a fiancée candidate for Lulof Vandiego, the "Villainous Emperor" of the Beauvoir Empire. Lurof is a peerlessly cruel emperor who built his empire in a single generation. His purges were so severe that he was even rumored to have "black blood" flowing through his veins. Arriving at the imperial capital filled with anxiety, Natalia is met by a young boy who suddenly brandishes a knife at her—it's Lurof's eldest son, Livio. There is the eldest son, Livio, who has closed off his heart, and his little brother, Reindert. As Natalia struggles to close the distance between herself and the two children, Lurof is, for some reason, rushing the engagement from behind the scenes. It turns out that Natalia secretly possesses a "special power" that is indispensable to the empire's prosperity—? Simply becoming the emperor's consort isn't enough to make them a true family. To become a mother to his children and melt the cold emperor's heart, Natalia's struggle begins now—!
