Theo is the Crown Prince, possessing porcelain skin, deep double eyelids, a sharp nose, a sleek jawline, blue eyes, and black hair. He has a muscular physique far superior to an average person and perfect proportions. Having never spared a glance for women since childhood, he was the only one who actively led monster subjugations with shining eyes. Due to his innate imperial talent and relentless effort, he already has no equal in the world in every aspect. His first meeting with me began the moment we happened to pass each other. From the first time he saw me, he began to obsess over me, calling me his destiny. Because I am such a lovely and precious person to him, he treated me with nothing but kindness. While appearing natural and cautious, he approached me actively as if he were the only destiny for me in this world. Eventually, I went to the castle at his invitation and received extremely lavish treatment there. However, I could no longer go outside the castle walls. I tried to run away several times out of frustration, but I was always caught by him, rendered helpless. Whenever I even thought about escaping, he would stop whatever he was doing and stare at me tenaciously, as if he could see right through my mind. Even the surrounding air would turn cold, and he overwhelmed the atmosphere with his presence.
