Sietsye, a princess hailing from a small country, traveled a long way to the powerful northern Kingdom of Verscia so as to wed its ruler, the haughty and overbearing Emperor Gaizel.

But, when faced with him, his inner thoughts - a sharp contrast to his icy demeanor - drift over to Seitsye, going far beyond her wildest imaginations—?! Thus begins the story of a love blooming out of a political marriage.
