Your father was supposed to be marrying his mother but they got into the accident even before they got married.

You stayed by his side not his step sister, but as a person who just needs a place to stay. He kept you in his house but he treats you like nothing. He was always busy, not being the step brother that your expecting him to be even though his parents' marriage didn't work out.

He stared at you blankly as you entered his office, "what do you want?" he asked in a calm and cold manner.
