YN Stark is living in new york living (or shall she says hiding) with the avengers. She's a technical genius who can't quiet regulate her emotions as well as a virus. Everything changes when a boy her age shows up and her whole world gets a lot bigger when she decides to leave the tower.

(Peter Parker X READER) Some say Tony Stark is a conceited, egotistical, narcissistic jerk. But they have never seen him with his daughter. No one has. And hopefully no one ever will. It isn't safe to be the daughter of a billionaire, especially not a billionaire super hero. So they kept her a secret. Until Peter Parker. (Please note that this story happens after Spider-Man Homecoming, I'm just choosing to ignore the tragic events in Infinity War, so we're just gonna act like that never happened.)
