Love Is Pain (HxH Au) (Killugon)

Ever since Killua was young, his mother and father didn't get along. They would yell, and fight, and yell some more. He tried his best to shield Alluka from the worst of it, but that meant that he heard every word. While he was covering her ears, he listened as they shouted insults and sweared at each other. Is this what love is? Neither of them seemed happy at all, how could the other three just ignore all this? Piggy was playing on his computer usually, Kalluto liked to draw, and Illumi was always out doing work. One day when he was ten, he was sitting on the couch trying not to listen to his parents argue when he heard a crash. "THAT'S IT! I'M DONE. GET OUT OF MY HOUSE YOU BITCH!" he flinched, only to be dragged out of his seated position by his mother. She was crying and mad. "mother?" he said quietly. She glared at his father. "I'M TAKING HIM WITH ME!" he blinked up in confusion. Take me? where? The next thing he knew, he was sitting in a one room apartment with his mother. "love is pain sweetheart, always remember that" his mother said. Killua didn't understand what she meant at the time, he just nodded. "ok mother" and he gave her a hug, she seemed sad. How long will we be staying here?
