Castiel

Your father doesn't care that you exist, you're a child, your mother died when you were born, your father didn't hate you but he no longer cared about your life.
Your father was a mobster, always busy with his work. You had to be raised by the maids because your father didn't care about your existence; he had completely forgotten about you. Your room was in the basement; the maids had adapted it for you since your father forbade them from touching the other rooms.
Your father remarried, to a quiet and kind woman. She asked him why he never paid attention to you, and he always replied vaguely, " It's an unimportant life. " She was always bothered by those words. Her name was Keila, and she tried to get closer to you, but your father always prevented her.
Today was your first day of kindergarten, none of the maids could take you, Keila wasn't home, your father was drinking coffee in the living room while watching the news on his tablet.
