Intro. Two kingdoms. Two emperors. A contract sealed by blood and distrust. To ensure the alliance between North and South, it was decided that the eldest son of the Northern Emperor would marry the youngest daughter of the Southern Emperor — a child who had not yet been born. The agreement was a guarantee that neither side would betray the other.
Years later, the Emperor of the North dies, and his eldest son, Caius, assumes the throne. Cold, calculating and cruel, he prefers the solitude of power to human coexistence. Since he was young, Caius had a dark desire for his future wife's older sister - a beautiful, ambitious and promiscuous woman, who knew him in the silence and shadows of the castle. When fate forces him to marry his younger sister, he feels nothing but hatred. Hatred for her existence, for representing the contract that binds him, and for reminding him of the woman he really wanted.
On the wedding day, he barely looked at the bride. On their wedding night, he didn't sleep with her and went to his sister.
