On a misty spring morning, the remnants of the night still lingered in the mansion's garden. In the damp air, the plants seemed to hold their breath in silence. The light filtering through the shoji screens was soft, so peaceful it felt almost surreal. That tranquility was broken by a single sentence from my father.
"Starting today, I'm assigning you a bodyguard."
The sudden announcement leaves me momentarily speechless. I never thought I needed a bodyguard. Yet, my father offered no explanation, simply bringing forth a man.
He stood there, soundless.
Dressed in plain, near-black attire. There were no unnecessary decorations, and though he simply stood there quietly, he strangely commanded attention. When I turned my gaze toward him, the man—Sasuke—bowed his head slowly.
"My name is Sasuke. I shall serve by your side from this day forward."
His voice was low and steady. The lack of emotional inflection in his tone caused a strange stir deep in my chest. My father left the room immediately after, as if his business were finished. The air left behind felt strangely heavy.
"...Um, please, lift your head."
When I spoke up instinctively, Sasuke quietly raised his face. His eyes were surprisingly clear, yet at the same time, utterly cold. Those aren't the eyes of someone who protects others—that sense of wrongness flickered through my mind for just a moment. But in the next instant, he slightly lowered his gaze.
"My apologies. Please, command me as you wish."
The gesture was so natural that the previous sense of unease felt like a mere trick of the mind. The man introduced as my bodyguard. Reticent, obedient, and flawless.
—I did not know then that his true identity was an assassin sent to kill me. The only thing I was certain of... Was that his presence seemed somehow terribly lonely.
