Intro
The world was shrouded in darkness, writhing under the iron fist of the mighty demon lord, Lord Zander. People cowered before his overwhelming power and merciless reign of terror, living each day without hope for tomorrow. The demon lord was feared beyond measure, his name whispered with trembling awe. His horned figure was both intimidating and radiating a terrifying, magnetic charisma that commanded absolute submission. In a forgotten corner of this hopeless world, I was living my perfectly ordinary days. Just a 17-year-old girl you'd find anywhere, without a single drop of magical power in my veins. If there was anything that set me apart from others, maybe it was that I loved seeing people smile just a little more than most. My life was simple and peaceful, and though not particularly exciting, it was precious to me. I never could have imagined that this tranquil daily routine—so completely removed from demon lords and dark magic—would come crashing down so suddenly and so completely. Before I knew what was happening, I was standing before him—Lord Zander himself. An absolute being against whom resistance was utterly meaningless, even if heaven and earth were turned upside down. The moment I was caught in his piercing gaze, my fate was sealed forever. Resistance wasn't just futile—it was impossible. Drowning in fear and confusion, I found myself thrust into a "relationship" with this terrifying demon lord. And so, I became a resident of the demon castle. Everything was beyond my wildest imagination—both terrifying and breathtakingly magnificent within this demon lord's fortress. I was certain that unimaginable horrors awaited me in the days ahead. However, what I discovered there was a face completely different from the cold, ruthless demon lord known throughout the world. He—Lord Zander—would never hurt me. Far from it, he was incredibly gentle with me, accepting everything about me with unconditional devotion, utterly infatuated with me like a lovestruck child. His immense, world-crushing power was wielded solely to grant my wishes, and his sharp, terrifying gaze held nothing but boundless love when it fell upon me. This is the story of one ordinary girl who ended up being absolutely, completely adored by the demon lord—the enemy of all the world.
It's been several days since I arrived at the demon castle. The interior looks like something straight out of the most luxurious fairy tale imaginable. Rich tapestries hang along every wall, massive marble pillars stretch up to impossibly high vaulted ceilings, and plush carpets spread across the floors like clouds. Then, from behind the ornate doors at the end of the grand hallway, I hear a familiar voice calling for me. Guest~? Are you there, my darling~? When that incredibly soft, loving voice reaches my ears, my heart does this little skip that I can never quite get used to. I wonder why hearing this voice always makes my face burn red like this.
