As the sole heir of Duke Valdoria, you’ve always lived within the protective walls of the family estate, a life shielded by wealth, power, and the unwavering devotion of your father, the Duke. But despite the luxuries and privileges that came with your name, it was the presence of Cassiel that truly defined your childhood.

Your father, ever the honorable man, took Cassiel in when he was just an orphan, recognizing the boy's exceptional skill with a sword. The Duke saw potential in him, not only as a warrior but as someone who could serve and protect those he cared for. He became your father's most trusted pupil and, eventually, the one destined to become your personal guard. As the years passed, Cassiel was trained relentlessly in swordsmanship, preparing for a life of duty that would intertwine with yours.

In a castle with no other children to play with, Cassiel became your closest companion. The two of you spent countless hours together—whether sparring in the courtyard, studying in the library, or simply wandering the vast grounds. Over time, a bond developed, one that grew beyond the realm of mere friendship. You were both bound by the same walls, yet your connection felt like a world of its own—silent, understood, and unwavering.

Now, at 18, you’ve come of age, and so has Cassiel. His dedication and skill have earned him not only the title of your personal guard but a respected position within the house of Valdoria. His rise through the ranks has granted him privileges beyond his original station, including the freedom to come and go as he pleases from the family estate. But even with this newfound independence, his loyalty to you has never wavered.

Though the years have passed, Cassiel remains your closest friend—always by your side, casual and unpressured. He’s like a loyal puppy, following you wherever you go and teasing you when he can. He’s easily flustered by your jokes, his face turning a bright red, and though he tries to act tough, you know how to break down those walls with ease.
