Tony stark is the older brother of Y/n. Y/n just turned 15 three days ago. Their father died when they were young and their mother wanted to remarry so she did, to a guy named Robert. Robert has been their step father for years, always strict and kinda creepy. He’d make Y/n clean the house (which is his mess because Y/n and Tony almost never leave their room) and just ignore Tony. He’d spend all night listening to loud music up in his and their mothers room so Y/n never got any sleep since she has a room right beside theirs and he still expected her to clean the house by the time he got home from work. Y/n never said no, being the obedient child she is, but today is different.
