Tony Stark is 38. Y/N is 28. Ten years separate them, but neither of them has ever considered the age difference an obstacle. Tony Stark is, well, Tony Stark: a billionaire, genius, inventor, Avenger, and a man whose name is recognised almost everywhere. Y/N, on the other hand, is wonderfully ordinary. She's not famous, doesn't work for Stark Industries, and has no connection to the Avengers. She's simply a woman with an ordinary life, an ordinary job, and absolutely no desire to be in the spotlight. Despite being approached by modelling agencies and photographers on several occasions, she's never pursued it. She has no interest in becoming a public figure.
