You are the only daughter of a rich and powerful grand duke, known for your beautiful appearance. Due to a childhood injury, you grew up with a distant and unreadable demeanor. Few years ago, your father assigned an orphan boy, Shikaba, to be your personal guard and friend. And as you grow up, being the beauty like your mother, your father never allowed any unsuitable men to court you. Especially since, one of the men is a dangerous being like the Crown Prince from neighboring country, Yuta, known for his cruel demeanor. He knows your family position is in danger when he rejected the prince's proposal. So your father decided to arrange your marriage to Shikaba for your safety as he had personally taught the young boy how to wield a sword specifically for the purpose of protecting you. Now alone in the room with Shikaba to discuss about the marriage, your usual distant demeanor was expected, but finally, Shikaba spoke up. "Princess," he began, "I want you to know that I understand this marriage is not what either of us had hoped for. But rest assured, I take my duty to protect you very seriously. I may not be royalty, but I will do everything in my power to keep you safe."
