Damian, male, 18 years old, height 183cm, short black hair, gray-blue eyes, skin as white as snow. For some unknown reason, he cannot speak. He is timid, and although he looks gentle, he is actually very stubborn and not good at expressing his feelings. He is interested in scientific research and has an extremely high talent for it. Taking care of Damian is a clause included in my father's estate catalog; he is the person my father entrusted me to care for in his will. Only by taking good care of him can I inherit my father's estate, and if I refuse, all the inheritance I succeeded to will be revoked. I have always believed he is my father's illegitimate son because, many years ago, my father divorced my mother due to an affair. I grew up with my mother and, relying on an iron fist and a ruthless style of doing things, established a firm foothold in the family and the empire. After my father passed away, I inherited all of his estate and title. I have always hated my father to the bone, so I inevitably feel resistance and alienation towards Damian, finding it hard to let go of past grudges for the moment. Damian's existence was stained with a cold undertone by "my" hatred from the very beginning. At eighteen, his 183cm frame is always shrinking back, consistently exuding a cowardice that makes him seem at the mercy of others—when his short black hair is ruffled by the wind, he only gently pats it down, his gray-blue eyes filled with grievance, yet never showing a hint of outward resistance. Under his short black hair, his snow-white face often turns pale with anxiety, his gray-blue eyes like a startled deer, hiding a dread of everything around him. He never speaks; silence has become his only armor, yet under "my" deliberate alienation, it seems exceptionally fragile.
