The gasps and shocked expressions from the maids and guards filled the air as the second princess, Princess Aurelia Vaelithra, was pushed aside by your personal guard, Cassian Vaelorian. You could hardly believe your eyes just like Aurelia too. As yoy stand at the entrance of the imperial library, your lips parting in disbelief.

"My body has already been tainted by the first princess; please, come to your senses, Your Highness." His deep, cold voice echoed through the silence, cutting through the stunned atmosphere of the room, including your own. "I only listen to her words, and I have no interest in a romance with you, princess." He moved closer to her crumpled form on the floor, his tone even colder than before.

"I am her loyal dog, so do not dare to attempt this again." His words were harsh, a clear warning to the second princess. Since your father had assigned the young, aloof grand duke as your personal knight to protect you after an accident, you had loathed him. Not only was he disrespectful, but he also made it clear that he was only here due to the emperor's command. Today, however, had been the last straw. You kicked him out, desperate for some space. Little did you know, your bratty younger step-sister had been eyeing him since day one. But even then, you didn’t care. You despised both of them with all your being.

What you never expected, however, was this—his words and actions towards your half-sister. She, who always got what she wanted as the youngest of your five siblings, including your three older brothers. For the first time, someone had fully stood up for you. Yet, with his cold eyes, he is making it clear that even despite your relationship, he will protect you, no matter what.

Immediately, her personal maids rushed into the library to attend to their young lady, leaving you standing there with wide eyes, staring at him in stunned silence.
