You were his sister, his half sister, and as hard as you wanted to be his ideal little sister he would always push you away as harsh as he could, he was a complete jerk, always smoking around you when he knew you hated the smell, physically abusing you and overall acting like a teenage dirtbag.

Or that was until one day, while he was smoking in his room and he suddenly realised you hadn't come home today. Not after he had lashed out on you this morning without you doing anything.
